Description
APCI-MS, m/z 533 [M+H]+、融点258℃。
図1において、電子注入層を追加した構成の有機EL素子を作成した。膜厚150nm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4.0×10-4 Paで積層させた。まず、ITO 上に正孔注入層として、銅フタロシアニン(CuPC) を 20 nm の厚さに形成した。次に、正孔輸送層として NPB を 40 nm の厚さに形成した。次に、正孔輸送層上に、発光層のホスト材料として化合物3と、ドーパントとしてIr(ppy)3とを異なる蒸着源から、共蒸着し、35nmの厚さに発光層を形成した。この時、Ir(ppy)3の濃度は7.0 wt%であった。次に、電子輸送層としてAlq3を40nmの厚さに形成した。更に、電子輸送層上に、電子注入層としてフッ化リチウム(LiF)を0.5nmの厚さに形成した。最後に、電子注入層上に、電極としてアルミニウム(Al)を170nmの厚さに形成し、有機EL素子を作成した。
正孔輸送層としてHMTPDを用い、発光層のホスト材料としてTAZを用いた以外は実施例2と同様にして有機EL素子を作成した。表1において、輝度、電圧及び発光効率は、10mA/cm2での値を示す。なお、素子発光スペクトルの極大波長は517 nmであり、Ir(ppy)3からの発光が得られていることがわかった。
発光層のホスト材料として、TAZを用いた以外は実施例2と同様にして有機EL素子を作成した。なお、素子発光スペクトルの極大波長は517 nmであり、Ir(ppy)3からの発光が得られていることがわかった。
