Description

化合物及びそれを用いた有機エレクトロルミネッセンス素子Compound and organic electroluminescence device using same
 本発明は、新規化合物及びそれを用いた有機エレクトロルミネッセンス素子に関する。 The present invention relates to a novel compound and an organic electroluminescence device using the compound.
 有機エレクトロルミネッセンス素子(以下、有機EL素子ともいう。)に電圧を印加すると、陽極から正孔が、また陰極から電子が、それぞれ発光層に注入される。そして、発光層において、注入された正孔と電子とが再結合し、励起子が形成される。 When a voltage is applied to an organic electroluminescence element (hereinafter also referred to as an organic EL element), holes are injected from the anode and electrons are injected from the cathode into the light-emitting layer. In the light-emitting layer, the injected holes and electrons recombine to form excitons.
 従来の有機EL素子は素子性能が未だ十分ではなかった。素子性能を高めるべく有機EL素子に用いる材料の改良は徐々に進められているが(特許文献1~4)、さらなる高性能化が求められている。  The performance of conventional organic EL elements is still insufficient. Although improvements to the materials used in organic EL elements have been gradually made to enhance element performance (Patent Documents 1 to 4), further improvements in performance are required.

[定義]
 本明細書において、水素原子とは、中性子数が異なる同位体、即ち、軽水素(protium)、重水素(deuterium)、及び三重水素(tritium)を包含する。
[Definition]
In this specification, hydrogen atoms include isotopes having different numbers of neutrons, namely protium, deuterium, and tritium.
 本明細書において、化学構造式中、「R」等の記号や重水素原子を表す「D」が明示されていない結合可能位置には、水素原子、即ち、軽水素原子、重水素原子、又は三重水素原子が結合しているものとする。 In this specification, in chemical structural formulas, any possible bonding position that is not explicitly indicated with a symbol such as "R" or "D" representing a deuterium atom is assumed to have a hydrogen atom, i.e., a protium atom, a deuterium atom, or a tritium atom, bonded to it.
 本明細書において、環形成炭素数とは、原子が環状に結合した構造の化合物(例えば、単環化合物、縮合環化合物、架橋化合物、炭素環化合物、及び複素環化合物)の当該環自体を構成する原子のうちの炭素原子の数を表す。当該環が置換基によって置換される場合、置換基に含まれる炭素は環形成炭素数には含まない。以下で記される「環形成炭素数」については、別途記載のない限り同様とする。例えば、ベンゼン環は環形成炭素数が6であり、ナフタレン環は環形成炭素数が10であり、ピリジン環は環形成炭素数5であり、フラン環は環形成炭素数4である。また、例えば、9,9-ジフェニルフルオレニル基の環形成炭素数は13であり、9,9’-スピロビフルオレニル基の環形成炭素数は25である。
 また、ベンゼン環に置換基として、例えば、アルキル基が置換している場合、当該アルキル基の炭素数は、ベンゼン環の環形成炭素数に含めない。そのため、アルキル基が置換しているベンゼン環の環形成炭素数は、6である。また、ナフタレン環に置換基として、例えば、アルキル基が置換している場合、当該アルキル基の炭素数は、ナフタレン環の環形成炭素数に含めない。そのため、アルキル基が置換しているナフタレン環の環形成炭素数は、10である。
In this specification, the number of ring carbon atoms refers to the number of carbon atoms among the atoms constituting the ring itself of a compound having a structure in which atoms are bonded in a ring (for example, a monocyclic compound, a fused ring compound, a bridged compound, a carbocyclic compound, and a heterocyclic compound). When the ring is substituted with a substituent, the carbon contained in the substituent is not included in the number of ring carbon atoms. The "number of ring carbon atoms" described below is the same unless otherwise specified. For example, a benzene ring has 6 ring carbon atoms, a naphthalene ring has 10 ring carbon atoms, a pyridine ring has 5 ring carbon atoms, and a furan ring has 4 ring carbon atoms. For example, a 9,9-diphenylfluorenyl group has 13 ring carbon atoms, and a 9,9'-spirobifluorenyl group has 25 ring carbon atoms.
In addition, when a benzene ring is substituted with, for example, an alkyl group as a substituent, the number of carbon atoms of the alkyl group is not included in the number of ring carbon atoms of the benzene ring. Therefore, the number of ring carbon atoms of the benzene ring substituted with an alkyl group is 6. In addition, when a naphthalene ring is substituted with, for example, an alkyl group as a substituent, the number of carbon atoms of the alkyl group is not included in the number of ring carbon atoms of the naphthalene ring. Therefore, the number of ring carbon atoms of the naphthalene ring substituted with an alkyl group is 10.
 本明細書において、環形成原子数とは、原子が環状に結合した構造(例えば、単環、縮合環、及び環集合)の化合物(例えば、単環化合物、縮合環化合物、架橋化合物、炭素環化合物、及び複素環化合物)の当該環自体を構成する原子の数を表す。環を構成しない原子(例えば、環を構成する原子の結合を終端する水素原子)や、当該環が置換基によって置換される場合の置換基に含まれる原子は環形成原子数には含まない。以下で記される「環形成原子数」については、別途記載のない限り同様とする。例えば、ピリジン環の環形成原子数は6であり、キナゾリン環の環形成原子数は10であり、フラン環の環形成原子数は5である。例えば、ピリジン環に結合している水素原子、又は置換基を構成する原子の数は、ピリジン環形成原子数の数に含めない。そのため、水素原子、又は置換基が結合しているピリジン環の環形成原子数は、6である。また、例えば、キナゾリン環の炭素原子に結合している水素原子、又は置換基を構成する原子については、キナゾリン環の環形成原子数の数に含めない。そのため、水素原子、又は置換基が結合しているキナゾリン環の環形成原子数は10である。 In this specification, the number of ring atoms refers to the number of atoms constituting the ring itself of a compound (e.g., a monocyclic compound, a fused ring compound, a bridged compound, a carbocyclic compound, and a heterocyclic compound) with a structure in which atoms are bonded in a ring (e.g., a monocyclic ring, a fused ring, and a ring assembly). The number of ring atoms does not include atoms that do not constitute a ring (e.g., a hydrogen atom that terminates the bond of an atom constituting a ring) or atoms contained in a substituent when the ring is substituted with a substituent. The "number of ring atoms" described below is the same unless otherwise specified. For example, the number of ring atoms of a pyridine ring is 6, the number of ring atoms of a quinazoline ring is 10, and the number of ring atoms of a furan ring is 5. For example, the number of hydrogen atoms or atoms constituting a substituent bonded to a pyridine ring is not included in the number of pyridine ring atoms. Therefore, the number of ring atoms of a pyridine ring to which a hydrogen atom or a substituent is bonded is 6. For example, hydrogen atoms bonded to carbon atoms in a quinazoline ring or atoms constituting a substituent are not included in the number of ring atoms in the quinazoline ring. Therefore, the number of ring atoms in a quinazoline ring to which a hydrogen atom or a substituent is bonded is 10.
 本明細書において、「置換もしくは無置換の炭素数XX~YYのZZ基」という表現における「炭素数XX~YY」は、ZZ基が無置換である場合の炭素数を表し、置換されている場合の置換基の炭素数を含めない。ここで、「YY」は、「XX」よりも大きく、「XX」は、1以上の整数を意味し、「YY」は、2以上の整数を意味する。 In this specification, the "carbon number XX to YY" in the expression "substituted or unsubstituted ZZ group having carbon numbers XX to YY" refers to the number of carbon atoms when the ZZ group is unsubstituted, and does not include the number of carbon atoms of the substituent when the ZZ group is substituted. Here, "YY" is larger than "XX", "XX" means an integer of 1 or more, and "YY" means an integer of 2 or more.
 本明細書において、「置換もしくは無置換の原子数XX~YYのZZ基」という表現における「原子数XX~YY」は、ZZ基が無置換である場合の原子数を表し、置換されている場合の置換基の原子数を含めない。ここで、「YY」は、「XX」よりも大きく、「XX」は、1以上の整数を意味し、「YY」は、2以上の整数を意味する。 In this specification, the "atomic number XX to YY" in the expression "substituted or unsubstituted ZZ group having atomic number XX to YY" refers to the atomic number when the ZZ group is unsubstituted, and does not include the atomic number of the substituent when the ZZ group is substituted. Here, "YY" is larger than "XX", "XX" means an integer of 1 or more, and "YY" means an integer of 2 or more.
 本明細書において、無置換のZZ基とは「置換もしくは無置換のZZ基」が「無置換のZZ基」である場合を表し、置換のZZ基とは「置換もしくは無置換のZZ基」が「置換のZZ基」である場合を表す。
 本明細書において、「置換もしくは無置換のZZ基」という場合における「無置換」とは、ZZ基における水素原子が置換基と置き換わっていないことを意味する。「無置換のZZ基」における水素原子は、軽水素原子、重水素原子、又は三重水素原子である。
 また、本明細書において、「置換もしくは無置換のZZ基」という場合における「置換」とは、ZZ基における1つ以上の水素原子が、置換基と置き換わっていることを意味する。「AA基で置換されたBB基」という場合における「置換」も同様に、BB基における1つ以上の水素原子が、AA基と置き換わっていることを意味する。
In this specification, the term "unsubstituted ZZ group" refers to the case where a "substituted or unsubstituted ZZ group" is an "unsubstituted ZZ group", and the term "substituted ZZ group" refers to the case where a "substituted or unsubstituted ZZ group" is a "substituted ZZ group".
In the present specification, "unsubstituted" in the case of "a substituted or unsubstituted ZZ group" means that a hydrogen atom in the ZZ group is not replaced with a substituent. The hydrogen atom in the "unsubstituted ZZ group" is a protium atom, a deuterium atom, or a tritium atom.
In the present specification, "substitution" in the case of "a substituted or unsubstituted ZZ group" means that one or more hydrogen atoms in the ZZ group are replaced with a substituent. Similarly, "substitution" in the case of "a BB group substituted with an AA group" means that one or more hydrogen atoms in the BB group are replaced with an AA group.

In this specification, the phrase "one or more of a set consisting of two or more adjacent groups bond to each other to form a substituted or unsubstituted monocycle, bond to each other to form a substituted or unsubstituted fused ring, or are not bonded to each other" means the case where "one or more of a set consisting of two or more adjacent groups bond to each other to form a substituted or unsubstituted monocycle", the case where "one or more of a set consisting of two or more adjacent groups bond to each other to form a substituted or unsubstituted fused ring", and the case where "one or more of a set consisting of two or more adjacent groups are not bonded to each other".
In this specification, the cases where "one or more of a set of two or more adjacent rings are bonded to each other to form a substituted or unsubstituted monocyclic ring" and "one or more of a set of two or more adjacent rings are bonded to each other to form a substituted or unsubstituted fused ring" (hereinafter, these cases may be collectively referred to as "a case where they are bonded to form a ring") will be explained below. The case of an anthracene compound represented by the following general formula (TEMP-103), in which the mother skeleton is an anthracene ring, will be explained as an example.
 例えば、R921~R930のうちの「隣接する2つ以上からなる組の1組以上が、互いに結合して、環を形成する」場合において、1組となる隣接する2つからなる組とは、R921とR922との組、R922とR923との組、R923とR924との組、R924とR930との組、R930とR925との組、R925とR926との組、R926とR927との組、R927とR928との組、R928とR929との組、並びにR929とR921との組である。 For example, in the case where "one or more pairs of adjacent two or more of R 921 to R 930 are bonded to each other to form a ring", the pair of adjacent two that constitutes one group includes the pair of R 921 and R 922 , the pair of R 922 and R 923 , the pair of R 923 and R 924 , the pair of R 924 and R 930 , the pair of R 930 and R 925 , the pair of R 925 and R 926 , the pair of R 926 and R 927 , the pair of R 927 and R 928 , the pair of R 928 and R 929 , and the pair of R 929 and R 921 .
 上記「1組以上」とは、上記隣接する2つ以上からなる組の2組以上が同時に環を形成してもよいことを意味する。例えば、R921とR922とが互いに結合して環Qを形成し、同時にR925とR926とが互いに結合して環Qを形成した場合は、前記一般式(TEMP-103)で表されるアントラセン化合物は、下記一般式(TEMP-104)で表される。 The above "one or more pairs" means that two or more pairs of the adjacent two or more pairs may simultaneously form a ring. For example, when R 921 and R 922 are bonded to each other to form a ring Q A , and R 925 and R 926 are bonded to each other to form a ring Q B , the anthracene compound represented by the general formula (TEMP-103) is represented by the following general formula (TEMP-104).
 「隣接する2つ以上からなる組」が環を形成する場合とは、前述の例のように隣接する「2つ」からなる組が結合する場合だけではなく、隣接する「3つ以上」からなる組が結合する場合も含む。例えば、R921とR922とが互いに結合して環Qを形成し、かつ、R922とR923とが互いに結合して環Qを形成し、互いに隣接する3つ(R921、R922及びR923)からなる組が互いに結合して環を形成して、アントラセン母骨格に縮合する場合を意味し、この場合、前記一般式(TEMP-103)で表されるアントラセン化合物は、下記一般式(TEMP-105)で表される。下記一般式(TEMP-105)において、環Q及び環Qは、R922を共有する。 The case where "a set of two or more adjacent rings" forms a ring includes not only the case where a set of "two" adjacent rings is bonded as in the above example, but also the case where a set of "three or more adjacent rings is bonded. For example, it means the case where R 921 and R 922 are bonded to each other to form a ring Q A , and R 922 and R 923 are bonded to each other to form a ring Q C , and a set of three adjacent rings (R 921 , R 922 and R 923 ) are bonded to each other to form a ring and are condensed to the anthracene skeleton. In this case, the anthracene compound represented by the general formula (TEMP-103) is represented by the following general formula (TEMP-105). In the following general formula (TEMP-105), ring Q A and ring Q C share R 922 .
 形成される「単環」、又は「縮合環」は、形成された環のみの構造として、飽和の環であっても不飽和の環であってもよい。「隣接する2つからなる組の1組」が「単環」、又は「縮合環」を形成する場合であっても、当該「単環」、又は「縮合環」は、飽和の環、又は不飽和の環を形成することができる。例えば、前記一般式(TEMP-104)において形成された環Q及び環Qは、それぞれ、「単環」又は「縮合環」である。また、前記一般式(TEMP-105)において形成された環Q、及び環Qは、「縮合環」である。前記一般式(TEMP-105)の環Qと環Qとは、環Qと環Qとが縮合することによって縮合環となっている。前記一般式(TMEP-104)の環Qがベンゼン環であれば、環Qは、単環である。前記一般式(TMEP-104)の環Qがナフタレン環であれば、環Qは、縮合環である。 The "monocyclic ring" or "fused ring" formed may be a saturated ring or an unsaturated ring as the structure of only the ring formed. Even if "one of the pairs of adjacent two" forms a "monocyclic ring" or a "fused ring", the "monocyclic ring" or the "fused ring" can form a saturated ring or an unsaturated ring. For example, the ring Q A and the ring Q B formed in the general formula (TEMP-104) are "monocyclic rings" or "fused rings", respectively. Furthermore, the ring Q A and the ring Q C formed in the general formula (TEMP-105) are "fused rings". The ring Q A and the ring Q C in the general formula (TEMP-105) are fused rings by the fusion of the ring Q A and the ring Q C. If the ring Q A in the general formula (TMEP-104) is a benzene ring, the ring Q A is a monocyclic ring. When ring Q 1 A in the above general formula (TMEP-104) is a naphthalene ring, ring Q 1 A is a fused ring.
 「不飽和の環」には、芳香族炭化水素環、芳香族複素環の他、環構造中に不飽和結合、即ち、二重結合及び/又は三重結合を有する脂肪族炭化水素環(例えば、シクロヘキセン、シクロヘキサジエン等)、及び不飽和結合を有する非芳香族複素環(例えば、ジヒドロピラン、イミダゾリン、ピラゾリン、キノリジン、インドリン、イソインドリン等)が含まれる。「飽和の環」には、不飽和結合を有しない脂肪族炭化水素環、又は不飽和結合を有しない非芳香族複素環が含まれる。
 芳香族炭化水素環の具体例としては、具体例群G1において具体例として挙げられた基が水素原子によって終端された構造が挙げられる。
 芳香族複素環の具体例としては、具体例群G2において具体例として挙げられた芳香族複素環基が水素原子によって終端された構造が挙げられる。
 脂肪族炭化水素環の具体例としては、具体例群G6において具体例として挙げられた基が水素原子によって終端された構造が挙げられる。
 「環を形成する」とは、母骨格の複数の原子のみ、あるいは母骨格の複数の原子とさらに1以上の任意の原子で環を形成することを意味する。例えば、前記一般式(TEMP-104)に示す、R921とR922とが互いに結合して形成された環Qは、R921が結合するアントラセン骨格の炭素原子と、R922が結合するアントラセン骨格の炭素原子と、1以上の任意の原子とで形成する環を意味する。具体例としては、R921とR922とで環Qを形成する場合において、R921が結合するアントラセン骨格の炭素原子と、R922とが結合するアントラセン骨格の炭素原子と、4つの炭素原子とで単環の不飽和の環を形成する場合、R921とR922とで形成する環は、ベンゼン環である。
The "unsaturated ring" includes aromatic hydrocarbon rings and aromatic heterocycles, as well as aliphatic hydrocarbon rings having an unsaturated bond in the ring structure, i.e., a double bond and/or a triple bond (e.g., cyclohexene, cyclohexadiene, etc.), and non-aromatic heterocycles having an unsaturated bond (e.g., dihydropyran, imidazoline, pyrazoline, quinolizine, indoline, isoindoline, etc.). The "saturated ring" includes an aliphatic hydrocarbon ring having no unsaturated bond, or a non-aromatic heterocycle having no unsaturated bond.
Specific examples of the aromatic hydrocarbon ring include structures in which the groups given as specific examples in the specific example group G1 are terminated with a hydrogen atom.
Specific examples of the aromatic heterocycle include structures in which the aromatic heterocyclic groups exemplified as specific examples in the specific example group G2 are terminated with a hydrogen atom.
Specific examples of the aliphatic hydrocarbon ring include structures in which the groups given as specific examples in the specific example group G6 are terminated with a hydrogen atom.
"Forming a ring" means forming a ring only with a plurality of atoms of the mother skeleton, or a plurality of atoms of the mother skeleton and one or more arbitrary atoms. For example, the ring QA formed by bonding R 921 and R 922 to each other in the general formula (TEMP-104) means a ring formed by the carbon atom of the anthracene skeleton to which R 921 is bonded, the carbon atom of the anthracene skeleton to which R 922 is bonded, and one or more arbitrary atoms. As a specific example, when R 921 and R 922 form a ring QA , when the carbon atom of the anthracene skeleton to which R 921 is bonded, the carbon atom of the anthracene skeleton to which R 922 is bonded, and four carbon atoms form a monocyclic unsaturated ring, the ring formed by R 921 and R 922 is a benzene ring.

In the arbitrary atom (for example, in the case of a carbon atom or a nitrogen atom), the bond that does not form a ring may be terminated with a hydrogen atom or the like, or may be substituted with an "arbitrary substituent" described below.

Specific examples of the “substituted or unsubstituted aromatic hydrocarbon ring having 6 to 50 ring carbon atoms” include compounds in which a hydrogen atom has been introduced into the “substituted or unsubstituted aryl group” described in specific example group G1.
Examples of the "heterocyclic ring" of ring a, ring b, and ring c include the same structures as the compounds in which a hydrogen atom has been introduced into the above-mentioned "heterocyclic group having 5 to 50 ring atoms".
The "heterocycle" of ring a contains three carbon atoms on the central fused bicyclic structure of formula (D3) as ring-forming atoms. The "heterocycle" of ring b and ring c contains two carbon atoms on the central fused bicyclic structure of formula (D3) as ring-forming atoms. Specific examples of the "substituted or unsubstituted heterocycle having 5 to 50 ring-forming atoms" include compounds in which a hydrogen atom has been introduced into the "substituted or unsubstituted heterocyclic group" described in specific example group G2.
 RD301及びRD302は、それぞれ独立に、a環、b環、又はc環と結合して、置換もしくは無置換の複素環を形成してもよい。この場合における複素環は、前記式(D3)の中央の縮合2環構造上の窒素原子を含む。この場合における複素環は、窒素原子以外のヘテロ原子を含んでいてもよい。RD301又はRD302がa環、b環又はc環と結合するとは、具体的には、a環、b環、又はc環を構成する原子と、RD301又はRD302を構成する原子と、が結合することを意味する。例えば、RD301がa環と結合して、RD301を含む環とa環が縮合した2環縮合、3環縮合、4環縮合、又は5環以上縮合の含窒素複素環を形成してもよい。当該含窒素複素環の具体例としては、具体例群G2のうち、窒素を含む2環縮合以上の複素環基に対応する化合物等が挙げられる。
 RD301がb環と結合する場合、RD302がa環と結合する場合、及びRD302がc環と結合する場合も上記と同じである。
R D301 and R D302 may each independently bond to the ring a, ring b, or ring c to form a substituted or unsubstituted heterocycle. The heterocycle in this case includes the nitrogen atom on the central fused two-ring structure of the formula (D3). The heterocycle in this case may include a heteroatom other than a nitrogen atom. Specifically, R D301 or R D302 bond to the ring a, ring b, or ring c means that an atom constituting the ring a, ring b, or ring c is bonded to an atom constituting R D301 or R D302 . For example, R D301 may bond to the ring a to form a two-ring fused, three-ring fused, four-ring fused, or five-ring or more fused nitrogen-containing heterocycle in which the ring containing R D301 is fused to the ring a. Specific examples of the nitrogen-containing heterocycle include compounds corresponding to the nitrogen-containing two-ring or more fused heterocyclic group in the specific example group G2.
The above applies when R D301 is bonded to ring b, when R D302 is bonded to ring a, and when R D302 is bonded to ring c.

(化合物の評価)
 実施例及び比較例の有機EL素子の製造においてホスト材料又はドーパント材料として用いた化合物について、一重項エネルギー(S)と三重項エネルギー(T)を以下のとおり測定した。結果を表1に示す。
(Evaluation of Compounds)
The singlet energy (S 1 ) and triplet energy (T 1 ) of the compounds used as host materials or dopant materials in the production of the organic EL devices of the Examples and Comparative Examples were measured as follows. The results are shown in Table 1.
・一重項エネルギーS
 測定対象となる化合物の10μmol/Lトルエン溶液を調製して石英セルに入れ、常温(300K)でこの試料の吸収スペクトル(縦軸:吸収強度、横軸:波長とする。)を測定した。この吸収スペクトルの長波長側の立ち下がりに対して接線を引き、その接線と横軸との交点の波長値λedge[nm]を次に示す換算式(F2)に代入して一重項エネルギーを算出した。
  換算式(F2):S[eV]=1239.85/λedge
 吸収スペクトル測定装置としては、日立社製の分光光度計(装置名:U3310)を用いた。
Singlet energy S 1
A 10 μmol/L toluene solution of the compound to be measured was prepared and placed in a quartz cell, and the absorption spectrum (vertical axis: absorption intensity, horizontal axis: wavelength) of this sample was measured at room temperature (300 K). A tangent line was drawn to the trailing edge on the long wavelength side of this absorption spectrum, and the wavelength value λ edge [nm] at the intersection of the tangent line and the horizontal axis was substituted into the following conversion formula (F2) to calculate the singlet energy.
Conversion formula (F2): S 1 [eV] = 1239.85/λ edge
The absorption spectrum measuring device used was a spectrophotometer manufactured by Hitachi Ltd. (device name: U3310).
 吸収スペクトルの長波長側の立ち下がりに対する接線は以下のように引く。吸収スペクトルの極大値のうち、最も長波長側の極大値から長波長方向にスペクトル曲線上を移動する際に、曲線上の各点における接線を考える。この接線は、曲線が立ち下がるにつれ(つまり縦軸の値が減少するにつれ)、傾きが減少しその後増加することを繰り返す。傾きの値が最も長波長側(ただし、吸光度が0.1以下となる場合は除く)で極小値をとる点において引いた接線を当該吸収スペクトルの長波長側の立ち下がりに対する接線とする。
 なお、吸光度の値が0.2以下の極大点は、上記最も長波長側の極大値には含めない。
The tangent to the fall on the long wavelength side of the absorption spectrum is drawn as follows. When moving on the spectral curve from the maximum value on the longest wavelength side among the maximum values of the absorption spectrum in the direction towards longer wavelengths, consider the tangent at each point on the curve. As the curve falls (i.e., as the value on the vertical axis decreases), the slope of this tangent decreases and then increases repeatedly. The tangent drawn at the point where the slope is at its minimum value on the longest wavelength side (excluding cases where the absorbance is 0.1 or less) is regarded as the tangent to the fall on the long wavelength side of the absorption spectrum.
Note that maximum points with absorbance values of 0.2 or less are not included in the maximum values on the longest wavelength side.
・三重項エネルギーT
 測定対象となる化合物をEPA(ジエチルエーテル:イソペンタン:エタノール=5:5:2(容積比))中に、10-5mol/L以上10-4mol/L以下となるように溶解し、この溶液を石英セル中に入れて測定試料とした。この測定試料について、低温(77[K])で燐光スペクトル(縦軸:燐光発光強度、横軸:波長とする。)を測定し、この燐光スペクトルの短波長側の立ち上がりに対して接線を引き、その接線と横軸との交点の波長値λedge[nm]に基づいて、次の換算式(F1)から算出されるエネルギー量を三重項エネルギーTとした。
換算式(F1):T[eV]=1239.85/λedge
Triplet energy T 1
The compound to be measured was dissolved in EPA (diethyl ether:isopentane:ethanol=5:5:2 (volume ratio)) to a concentration of 10 -5 mol/L or more and 10 -4 mol/L or less, and this solution was placed in a quartz cell to prepare a measurement sample. The phosphorescence spectrum (vertical axis: phosphorescence emission intensity, horizontal axis: wavelength) of this measurement sample was measured at low temperature (77 [K]), a tangent was drawn to the rising edge on the short wavelength side of this phosphorescence spectrum, and the amount of energy calculated from the following conversion formula (F1) based on the wavelength value λ edge [nm] at the intersection of the tangent and the horizontal axis was defined as the triplet energy T1 .
Conversion formula (F1): T 1 [eV] = 1239.85/λ edge
 燐光スペクトルの短波長側の立ち上がりに対する接線は以下のように引いた。燐光スペクトルの短波長側から、スペクトルの極大値のうち、最も短波長側の極大値までスペクトル曲線上を移動する際に、長波長側に向けて曲線上の各点における接線を考える。この接線は、曲線が立ち上がるにつれ(つまり縦軸が増加するにつれ)、傾きが増加する。この傾きの値が極大値をとる点において引いた接線(すなわち変曲点における接線)が、当該燐光スペクトルの短波長側の立ち上がりに対する接線とした。
 なお、スペクトルの最大ピーク強度の15%以下のピーク強度をもつ極大点は、上述の最も短波長側の極大値には含めず、最も短波長側の極大値に最も近い、傾きの値が極大値をとる点において引いた接線を当該燐光スペクトルの短波長側の立ち上がりに対する接線とした。
 燐光の測定には、株式会社日立ハイテク製のF-7100形分光蛍光光度計本体を用いた。
The tangent to the rising edge of the phosphorescence spectrum on the short wavelength side was drawn as follows. When moving along the spectral curve from the short wavelength side of the phosphorescence spectrum to the shortest maximum of the spectral maxima, a tangent to each point on the curve toward the long wavelength side was considered. The slope of this tangent increases as the curve rises (i.e., as the vertical axis increases). The tangent drawn at the point where this slope is at its maximum (i.e., the tangent at the inflection point) was taken as the tangent to the rising edge of the phosphorescence spectrum on the short wavelength side.
Note that a maximum point having a peak intensity of 15% or less of the maximum peak intensity of the spectrum was not included in the maximum value on the shortest wavelength side described above, and a tangent drawn at a point where the slope value is the maximum value that is closest to the maximum value on the shortest wavelength side was defined as a tangent to the rising edge on the short wavelength side of the phosphorescence spectrum.
The phosphorescence was measured using a Hitachi High-Tech F-7100 spectrofluorophotometer.
