一种新型金属铱(Ⅲ)类磷光材料的合成及性能研究
Synthesis and Characterization of a New Phosphorescent Iridium(Ⅲ)Complex
【摘要】 以邻氨基苯硫酚、苯甲酰氯为起始原料,通过与三氯化铱配合反应,合成了一种新型金属铱的(2-苯基苯并噻唑)配合物(bt)2Ir(acac),产率为45.47%,熔点为303~304℃。通过质谱、元素分析及红外光谱对其结构进行了表征,并对其光致发光性质进行了研究。研究表明,配合物在350~450nm存在单线态和三线态金属铱到配体的电荷跃迁,在566.0 nm处有强的金属配合物三线态磷光发射,配合物(bt)2Ir(acac)是一种新型的磷光材料。
【Abstract】 A new phosphorescent(2-phenyl)-benzothiazolate iridium(Ⅲ)acetylacetone complex is synthe- sized with 2-aminothiophenol,benzoyl-chloride and iridium trichloride anhydrate.The yield of the complex is 45.47 and the melting point in the range of 303~304℃.The complex is characterized by mass spectrometry,FT-IR and ele- mental analysis.The complex shows strong singlet and triplet metal to ligand charge-transfer from 350ran to 450nm. The complex also produces a strong photoluminescence at 566.0nm,It suggests that the complex is a new phosphores- cent material.
