Received Date: 26 September 2003

Fund Project: The research was supported by NHTRDP (863 Program) of China (No. 2002AA324080).

A new cyclometalated iridium(Ⅲ) complex with the formula [Ir(DPQ)₂(acac)] (DPQ=2,3-diphenylquinoxaline; acac=acetylacetone) was prepared. The structure of the complex was confirmed by Elemental Analysis (EA), ¹H NMR, and mass spectroscopy (MS). The UV-vis absorption and photoluminescent properties of the complex were investigated.
