Description
下記反応式1の反応経路によって化学式19で表される化合物19を合成した。
中間体(a)の合成
2−ブロモ−6−メトキシナフタレン7.5g(32mmol)、フェノキサジン4.6g(25mmol)、ナトリウムtert−ブトキシド3.7g(38mmol)、(Pd2(dba))3 (トリス(ジベンジリジンアセトン)ジパラジウム(0))0.3g(0.33mmol)、及びトリ(tert−ブチル)ホスフィン0.11g(0.55mmol)をトルエン125mlに溶解させた後、80℃で12時間反応させた。
中間体(a)3.39g(10mmol)をCHCl3 150mlに溶解させた後、0℃に維持しつつ、NBS(N−ブロモスクシンイミド)の存在下、中間体(a)に1.1当量の臭素をゆっくり添加した。出発物質が完全に溶解したことを薄層クロマトグラフィー(thin layer chromatography:TLC)で確認した時点で、前記混合物への臭素添加を中止し、反応混合物を10分間撹拌した後、反応を停止させた。
50mlの丸底フラスコ中で、前記中間体(b)1.095g(1.0eq、2.72mmol)をTHF10mlに溶かした後、−78℃まで冷却した。この溶液に、2.2ml(2.0eq、5.44mmol)のn−BuLi 2.5M(ヘキサン)を徐々に滴加した後、−78℃に維持しつつ30分撹拌し、2−イソプロポキシ−4,4,5,5−テトラメチル−1,3,2−ジオキサボロラン1.1ml(2.0eq、5.44mmol)を添加した後で撹拌しつつ、反応温度を徐々に、1時間30分かけて常温まで上げた。常温で30分間更に撹拌した後、水10mlと酢酸エチル10mlとで抽出した。水溶液層をCHCl3 10mlで抽出した後、有機層を加えてMgSO4で乾燥濃縮し、混合比3:22の酢酸エチル及びヘキサンの混合溶液を展開液とするシリカカラムクロマトグラフィーにより、中間体(c)0.76g(60%)を分離した。中間体(c)の構造は、1H−NMRを介して確認した。
前記中間体(c)100mg(0.215mmol)をTHF1mlに溶解させた後、1,4−ジブロモベンゼン24.6mg(0.086mmol)、テトラキス(トリフェニルホスフィン)パラジウム(0)10mg(0.009mmol)を2mlのトルエン中に溶解させた。この混合溶液に20%テトラエチルアンモニウム水溶液2mlを添加した後、100℃で24時間撹拌した。常温まで冷却した後、吸着シリカゲルカラムクロマトグラフィーにより分離精製し、化合物19を69.0mg(収率:95%)得た。化合物19の構造は、1H−NMRを介して確認した。
以下に示される方法により、化学式5で表される化合物5を合成した。
以下に示される方法により、化学式17で表される化合物17を合成した。
化合物のUV吸収スペクトル及びPL(photoluminescence)スペクトルを評価することにより、各化合物の発光特性を評価した。まず、化合物5をトルエンで0.2mMの濃度に希釈し、(株)島津製作所のUV−350スペクトロメータ(Shimadzu UV−350 Spectrometer)を利用し、UV吸収スペクトルを測定した。化合物7、9、11、17、18、19、20及び21についても同様に測定した。一方、化合物5をトルエンで10mMの濃度に希釈し、キセノン(Xenon)ランプが装着されているISC PC1スペクトロフロオロメータ(Spectrofluorometer)を利用し、PLスペクトルを測定した。その結果を下記表1に表した。
化学式19で表される化合物19を発光層のドーパントとして使用し、化学式23で表される化合物23(AND)を発光層のホストとして使用し、次のような構造を有する有機発光素子を製作した。すなわち、ITO上にPEDOT(50nm(500Å))、AND及び化合物19(48nm(480Å))、Alq3(20nm(200Å))、LiF(1nm(10Å))並びにAl(200nm(2,000Å))を順次に積層させた構造を有する。
ANDホストを使用せずに、化合物19だけを発光層として使用したことを除いては、前記実施例1と同じ方法でITO上にPEDOT(50nm(500Å))、化合物19(48nm(480Å))、Alq3(20nm(200Å))、LiF(1nm(10Å)及び/Al(200nm(2,000Å))を順次積層させた構造を有する有機発光素子を製造した。これをサンプル2とする。
ドーパントとして化合物19の代わりに化合物17を利用したという点を除いては、前記実施例1と同じ方法で、ITO上にPEDOT(50nm(500Å))、AND及び化合物17(48nm(480Å))、Alq3(20nm(200Å))、LiF(1nm(10Å))並びにAl(200nm(2,000Å))を順次積層させた構造を有する有機発光素子を製造した。これをサンプル3とする。
ホストとしてAND、ドーパントとして前記化学式22で表される化合物22(DPAVBi)を利用したという点を除いては、前記実施例1と同じ方法で、ITO上にPEDOT(50nm(500Å))、AND及び化合物22(48nm(480Å))、Alq3(20nm(200Å))、LiF(1nm(10Å))並びにAl(200nm(2,000Å))を順次積層させた構造を有する有機発光素子を製造した。これをサンプル4とする。
サンプル1、2、3及び比較サンプル4に対し、PR650(Spectroscan)Source Measurement Unitを利用して駆動電圧、色純度、効率をそれぞれ評価し、その結果を下記表2に表した。
