In this study, three excellent yellow emissive Cu(I) complexes were synthesized, namely [Cu2I2(bipy)(POP)2]·4CH2Cl2 (1), [Cu2Br2(bipy)(POP)2]·4CH2Cl2 (2), and [CuCl(bipy)(POP)]·CH2Cl2·CH3OH (3) [bipy = 4,4′-bipyridine, POP = bis(2-diphenylphosphino-phenyl)ether]. The synthesis and characterization of three complexes are introduced. Complexes 1–3 have luminescent emission peaks of 529–532 nm, belonging to yellow light emission, and their quantum yield is 72–88%. Complex 2 exhibits an exceptionally high quantum yield of 88% and its lifetime is 9.6 μs. Among the available data, this result is one of the best luminescence results for yellow luminescent cuprous complexes. This study enriches the understanding of the photophysical properties of Cu(I) complexes and offers new insights for the development of efficient OLED materials.

三种基于二膦配体和二亚胺配体的优异黄光Cu(I)配合物的合成及发光性能
本研究合成了三种优异的黄色发射Cu( I )配合物，即[Cu 2 I 2 (bipy)(POP) 2 ]·4CH 2 Cl 2 ( 1 )、[Cu 2 Br 2 (bipy)(POP) ] 2 ]·4CH 2 Cl 2 ( 2 )、[CuCl(bipy)(POP)]·CH 2 Cl 2 ·CH 3 OH ( 3 ) [bipy = 4,4′-联吡啶，POP = 双(2-二苯基膦) -苯基)醚]。介绍了三种配合物的合成和表征。配合物1~3的发光峰为529~532 nm，属于黄光发射，量子产率为72~88%。配合物2表现出 88% 的极高量子产率，其寿命为 9.6 μs。在现有数据中，该结果是黄色发光亚铜配合物的最佳发光结果之一。这项研究丰富了对Cu( I )配合物光物理性质的理解，并为高效OLED材料的开发提供了新的见解。
