nm. The combined experimental and density functional theory results suggest that the luminescence of the complexes represents phosphorescence attributed to the 3(M + X)LCT transitions. The prototype solution-processed devices with the complexes as an emitting dopant realize high electroluminescent performance. In particular, the OLED based on 3 achieves a maximum EQE value of 3.08%, which is equivalent

磷光四配位Cu(I)配合物(1-3)和特点。在紫外线激发下,固态的标题配合物在290 K时呈现强发射,光致发光量子产率为35%,衰变时间短(τ <11μs)。甲氧基的参与使得光致发光的调谐成为可能。最大值从568到589 nm。实验和密度泛函理论的组合结果表明,配合物的发光表示归因于3的磷光。(M + X)LCT转换。以络合物作为发射掺杂剂的原型溶液处理器件实现了高电致发光性能。特别是,基于3的OLED达到3.08%的最大EQE值,相当于各自理论最大值的52%,这表明廉价和环境性的亚铜配合物是发光贵
金属配合物的潜在替代品。
