采用微波辐射方法,由2-苯基喹喔啉(PQ)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(PQ)3](PQ=2-苯基喹喔啉),通过1H NMR、元素分析和质谱方法对配合物进行了表征,并研究了配合物的紫外吸收光谱和光致发光光谱.结果表明,配合物Ir(PQ)3在476 nm和607am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625 nm处有较强的金属配合物三线态的磷光发射.是一种新型红色三线态磷光材料.

A novel cyclometalated iridium （III） quinoxaline complex with the formula Ir （PQ）3 （PQ=2- phenylquinoxaline） was prepared by microwave assisted synthesis. The complex was characterized by elemental analysis, ^1H NMR and mass spectroscopy. The complex showed strong ^1MLCT （singlet metal to ligand charge- transfer） and 3MLCT （triplet metal to ligand charge-transfer） absorption at 476 nm and 607 nm, respectively. It also showed strong photoluminescence at 625 nm at room temperature. The results suggested the compl...
