摘要：

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.
