Me8HQ 8.0gと重水77gを10%パラジウム-炭素触媒0.1gとともに100mLオートクレーブに装填し、180℃で2時間加熱攪拌して反応を実施した。反応終了後、触媒をろ過した後、トルエンを加えて油水分離を行い、更に水層をトルエンにて抽出、得られた有機層を無水硫酸マグネシウムにて乾燥後、溶媒を除去して粗製物得た。この粗製物を減圧蒸留にて精製してMe8HQ-D 7.6g(収率92%)を得た。
Me8HQ 16.0gと重水140gを10%パラジウム-炭素触媒0.016gとともに200mLオートクレーブに装入し、180℃で2時間加熱攪拌して反応を実施した。合成例1と同様に分離、精製を行い、Me8HQ-D 14.6g(収率88%)を得た。
Me8HQ 16.0gと重水140gを10%パラジウム-炭素触媒0.016gとともに200mLオートクレーブに装入し、140℃で2時間加熱攪拌して反応を実施した。合成例1と同様に分離、精製を行い、Me8HQ-D 14.9g(収率90%)を得た。
100mL三口フラスコ中に合成例1で調製したMe8HQ-D1(1.1g)、アルミニウムトリイソプロポキシド(1.2g)、トルエン20mLを装入し攪拌する。この懸濁液に、トルエン12mLに溶解した4−ヒドロキシビフェニル(2.0g)をしたのち、2時間加熱還流する。冷却後、生じた沈殿を濾取、乾燥して粗製物(2.7g)を得た。得られた粗製物を昇華精製して、BAlq-D 2.2g(収率71%)を得た。

正孔注入層に銅フタロシアニン(CuPC)を用い、正孔輸送層にα-NPD及び電子輸送層にAlq3を用いた。膜厚110nmのITOからなる陽極が形成されたガラス基板上に、各薄膜を真空蒸着法にて、真空度5.0×10-4 Paで積層させた。まず、ITO上に正孔注入層としてCuPCを3.0Å/秒で25nmの膜厚で成膜した。次いで、正孔注入層上に、正孔輸送層としてα-NPDを蒸着速度3.0Å/秒にて55nmの厚さに形成した。
次に、正孔輸送層上に、発光層としてホスト材料としての合成例4で得たBAlq-D4とIr(piq)3(化合物44)とを異なる蒸着源から共蒸着し、47.5nmの厚さに形成した。この時、Ir(piq)3の濃度は8.0 %であった。
