Description
以下、本発明に関し詳細に説明する。
本発明のアミン誘導体は、有機EL素子の正孔注入材料、正孔輸送材料又は発光層のホスト材料としても利用可能であるが、特に正孔輸送材料として使用した際に、従来の材料以上に駆動電圧の改善と高い電力効率が期待できる。また、本発明のアミン誘導体は、カルバゾール基を部分構造に持ちながらもベンゾフルオレニル基の11位に結合した置換基により、材料自身の結晶化が抑制されることから、有機EL素子の耐久性向上も期待できる。
・機器 :東ソー製 マルチステーションLC−8020

実施例1(化合物A2の合成)
窒素置換した200mLの3つ口フラスコに、中間体3 3.0g(7.0mmol)、合成例4で合成したN−フェニル−9−アミノ−11,11−ジメチル−11H−ベンゾ[a]フルオレン 2.81g(8.4mmol)、酢酸パラジウム16mg(0.071mmol)、ナトリウムターシャリーブトキシド 0.81g(8.4mmol)、o−キシレン 60mLを加えた。最後にトリ−tert−ブチルホスフィン 68mg(0.34mmol)を加え、130℃に加熱した。14時間後、加熱を終了し、室温まで放冷した。この反応液を純水(60mL×2)、飽和NaCl溶液(30mL)で洗浄し、得られた有機層を無水硫酸マグネシウムで乾燥した。有機層濃縮残渣をシリカゲルカラムクロマトグラフィーで精製し(展開溶媒トルエン/ヘキサン)、更にトルエンで2回再結晶することにより、白色粉末3.30gを得た(収率54%,HPLC純度=99.5%)。
