摘要： 采用微波辐射加热方法，将2，3-二苯基喹喔啉（DPQ）与水合三氯化铱（IrCl3•H2O）反应，合成了一种新型三环喹喔啉铱配合物[Ir(DPQ)3]，通过元素分析，1H NMR和质谱方法对配合物结构进行了表征，并初步研究了配合物的吸收光谱和荧光光谱。结果表明，配合物Ir(DPQ)3在387和458nm处存在单线态1MLCT（金属到配体的电荷跃迁）和三线态3MLCT的吸收；在634nm 处有较强的金属配合物三线态的磷光发射。

Abstract: Microwave-assisted synthesis of a novel cyclometalated iridium(III) quinoxaline complex with the formula Ir(DPQ)3(DPQ=2,3-diphenylquinoxaline) via the reaction of 2,3-diphenylquinoxaline and iridium trichloride hydrate. The complex was characterized by elemental analysis, 1H NMR and mass spectroscopy. The complex shows strong 1MLCT (singlet metal to ligand charge-transfer) and 3MLCT (triplet metal to ligand charge-transfer) absorption at 387 and 458nm, respectively. The complex also shows strong photoluminescence at 634nm at room temperature. These results suggest the complex to be a promising phosphorescent material.

Key words: phosphorescent material, iridium quinoxaline complex, triplet, microwave-assisted synthesis
