合成了一个新的双核铕配合物Eu(TTA)3(tpphz)Eu(TTA)3(其中TTA＝去质子化的α-噻吩甲酰三氟丙酮; tpphz＝[3,2-a:2',3'-c:3'',2''-h:2''',3'''-j]四吡啶基吩嗪). 研究了该配合物的光致发光和电致发光性质. 一个四层电致发光器件ITO/TPD, 10 nm/Eu(TTA)3(tpphz)Eu(TTA)3, 20 nm/BCP, 20 nm/AlQ, 40 nm/Mg0.9Ag0.1, 200 nm/Ag, 100 nm表现出中心在633 nm处的宽带红光发射, 该宽带发射可能来源于双核Eu(III)配合物和TPD形成的激基复合物. 该器件的启动电压为10 V, 在18 V和135 mA/cm2时的最大亮度达146 cd/m2.

A binuclear europium(II) complex of Eu(TTA)3(tpphz)Eu(TTA)3 (where tpphz＝tetrapyrido- [3,2-a:2',3'-c:3'',2''-h:2''',3'''-j]phenazine; TTA＝α-thenoyltrifluoroacetonato) was newly synthesized. The photoluminescent and electroluminescent properties of the complex were studied. A four-layered device of ITO/TPD, 10 nm/Eu(TTA)3(tpphz)Eu(TTA)3, 20 nm/BCP, 20 nm/AlQ, 40 nm/Mg0.9Ag0.1, 200 nm/Ag, 100 nm gave a wide emission peak centered at 633 nm, which was most probably due to the formation of the exciplex between the Eu(III) complex and TPD. The maximum luminance of 146 cd/m2 at 18 V and 135 mA/cm2, and a turn-on voltage of 10 V were achieved for the device.
