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、1HNMR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和三线态3MLCT(金属到配体的电荷跃迁)的吸收;在634nm处有较强的金属配合物三线态的磷光发射。 Microwave-assisted synthesis of a novel cyclometalated iridium（Ⅲ ） quinoxaline complex with the formula Ir（ DPQ）3 （DPQ = 2,3-diphenylquinoxaline ） was performed via the reaction of DPQ and iridium trichloride hydrate. The complex was characterized by elemental analysis, 1H NMR and mass spectrometry. The complex shows strong J MLCT （ singlet metal to ligand charge-transfer） absorption at 387 and 3 MLCT （triplet metal to ligand charge-transfer） absorption at 458 nm, respectively. The complex also shows strong photoluminescence at 634 nm at room temperature. These results suggest that the complex is a promising phosDhorescent material.
