摘    要:以2-(2’-苯并噻吩基)吡啶(btp)、对乙烯基苯甲酸(VBA)为原料,通过与水合三氯化铱(IrCl3·3H2O)配合,得到了一种新型铱(Ⅲ)配合物Ir(btp)2(VBA),通过元素分析、FT—IR光谱及^1HNMR谱对其进行了结构表征,并研究了其UV—Vis吸收光谱和光致发光光谱。结果表明,配合物在403和462nm处存在单重态和三重态的吸收峰,在630nm处有较强的金属配合物三重态的磷光发射峰,是一种新型红色磷光材料。

关 键 词:磷光材料  重金属配合物  三重态

Abstract:A novel red phosphorescent Iridium ( Ⅲ) complex Ir ( btp ) 2 ( VBA ) was synthesized with 2 - ( 2' - benzothienyl) pyridine ( btp), 4 - vinylbenzoie (VBA) and iridium triehloride hydrate. It was characterized by elemental analysis, FT - IR and i H NMR. The UV - Vis absorption and photoluminescence of the complex were investigated. The complex showed strong 1MLCT( single metal to ligand charge -transfer ) and 3MLCT (triple metal to ligand charge -ransfer) absorption at 403 and 462 nm, respectively. It also exhibted a strong photoluminescence at 630 nm at room temperature. These results showed that the complex was a promising red phosphorescent material.
Keywords:phosphorescent material  heavy metal complex  triplet
