A series of highly emissive three-coordinate copper(I) complexes, (dtpb)Cu(I)X [X = Cl (1), Br (2), I (3); dtpb =1,2-bis(o-ditolylphosphino)benzene], were synthesized and investigated in prototype organic light-emitting diodes (OLEDs). 1-3 showed excellent photoluminescent performance in both degassed dichloromethane solutions [quantum yield (Φ) = 0.43-0.60; lifetime (τ) = 4.9-6.5 μs] and amorphous films (Φ = 0.57-0.71; τ = 3.2-6.1 μs). Conventional OLEDs containing 2 in the emitting layer exhibited bright green luminescence with a current efficiency of 65.3 cd/A and a maximum external quantum efficiency of 21.3%.
一系列高辐射的三配位铜（I）配合物，（dtpb）Cu（I）X [X = Cl（1），Br（2），I（3）；dtpb = 1,2-双（邻二甲苯膦基）苯]，被合成并在原型有机发光二极管（OLEDs）中进行了研究。1-3 在脱气的二氯甲烷溶液中表现出优异的光致发光性能[量子产率（Φ）= 0.43-0.60；寿命（τ）= 4.9-6.5 μs]和非晶薄膜中（Φ= 0.57-0.71；τ= 3.2-6.1 μs）。含有 2 的传统 OLED 作为发射层，表现出明亮的绿色发光，电流效率为 65.3 cd/A，最大外量子效率为 21.3%。
