研制出了一种新型的Cu(Ⅰ)配合物[Cu(DPEphos)(PyPPN)]BF4(CuL1L2),其中二DPEp-hos和PyPPN分别表示(2-二苯基膦基)苯基醚和吡啶并[1′,2′∶2,3]吡嗪[5,6-f]1,10-菲罗啉,并制备了结构为ITO(20Ω)/2-TNATA(20nm)/NPB(40nm)/CBP∶8%CuL1L2(30nm)/BCP(20nm)/Alq3(20nm)/LiF(1nm)/Al(100nm)的掺杂式有机发光二极管(OLED)。掺杂式器件在530nm处有较强的金属配合物三重态的绿光电致磷光(ELECTROPHOS-PHORESCENCE,EPL)发射,最大亮度为2388cd/m2,在电流为0.1mA时,器件的最大电流效率达到11.4cd/A,据我们所知,该OLED器件的EL性能是目前报道Cu(Ⅰ)磷光配合物的EPL器件中最高的。
A new type of Cu (Ⅰ) complex [Cu (DPEphos) (PyPPN)] BF4 (CuL1L2) has been developed, in which two DPEp-hos and PyPPN represent (2-diphenylphosphino) phenyl ether and pyridine (20Ω) / 2-TNATA (20nm) / NPB (40nm) with the structure of [1 ’, 2’:2,3] pyrazine [5,6-f] / CBP: 8% CuL1L2 (30 nm) / BCP (20 nm) / Alq3 (20 nm) / LiF (1 nm) / Al (100 nm). The maximum emission current of the device is 2388cd / m2 at 530nm with ELECTROPHOS-PHORESCENCE (EPL) emission of metal complex triplet. The maximum current efficiency of the device reaches 11.4 cd / A, to our knowledge, the EL performance of this OLED device is the highest of the EPL devices currently reported for Cu (I) phosphorescent complexes.
