摘    要: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^1HNMR、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476nm和607nm处存在单线态。MLCT(金属到配体的电荷跃迁)和三线态。MLCT的吸收;在625nm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。

关 键 词:金属铱配合物  微波合成  光致发光

Abstract: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 complex be a promising triplet phosphorescent material.
Keywords:iridium quinoxaline complex  microwave-assisted synthesis  photoluminescence
