A novel Cu-NHC based phosphorescent binuclear iridium(iii)/copper(i) complex has been prepared. The copper(i) center adopts an unpredictable near-linear two-coordination mode with short Cu-N and Cu-C bond lengths and two obvious CH-π interactions, which support its stability in the solid state. It also shows better optical properties (higher luminescence efficiency and shorter emission lifetime) in both solution and solid states relative to the model binuclear copper(i)/copper(i) complex, and was successfully applied in solution-processed organic light-emitting diodes.
一种新型的基于 Cu-NHC 的磷光双核铱(III)/铜(I)配合物已被制备。铜(I)中心采用一种不可预测的近线性二配位模式，具有短的 Cu-N 和 Cu-C 键长以及两个明显的 CH-π 相互作用，这支持了其在固态中的稳定性。与模型双核铜(I)/铜(I)配合物相比，它在溶液和固态中均表现出更好的光学性能（更高的发光效率和更短的发射寿命），并成功应用于溶液处理的有机发光二极管中。
