The photophysical properties of several Cu(I) complexes coordinated with cyclic (alkyl)(amino)carbene (CAAC) ligands were examined. All the compounds were found to be phosphorescent, regardless of whether they are 2-, 3- or 4-coordinated. Aggregate and excimer emission were observed from 2-coordinate CAAC–CuCl derivatives in methylcyclohexane solution. Emission from the complex 4-coordinated with a trispyrazolylborate ligand is red-shifted with respect to both the chloro-derivative and an analogous complex with an NHC ligand.

磷光的2、3和4配位环状（烷基）（氨基）卡宾（CAAC）Cu（I）配合物

研究了几种与环状（烷基）（氨基）卡宾（CAAC）配体配位的Cu（Ⅰ）配合物的光物理性质。发现所有化合物都是磷光的，无论它们是2-，3-或4-配位的。在甲基环己烷溶液中，从2-配位CAAC-CuCl衍生物观察到聚集体和受激准分子的发射。与三吡唑基硼酸酯配体配合的配合物4-的发射相对于氯衍生物和具有NHC配体的类似配合物都发生红移。
