新型红色磷光铱（Ⅲ）配合物的合成及表征

Synthesis and Characterization of a Novel Red Phosphorescent Iridium （Ⅲ） Complex

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。

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.
