摘要
利用2-对甲苯基吡啶(ptpy)、对乙烯基苯甲酸(VBA)和三水合氯化铱(IrCl3.H2O)配位,得到了铱配合物Ir(ptpy)2(VBA)。通过元素分析、FTIR光谱、1HNMR谱对其进行了结构表征,结果显示得到的是目标化合物。对配合物的吸收光谱和光致发光光谱进行了研究。结果表明,配合物在400nm和450nm处存在单重态和三重态的吸收峰,在523nm处有较强的金属配合物三重态的磷光发射峰,是一种新型绿色磷光材料。
A new iridium pyridine complex Ir (ptpy)2(VBA) was synthesized by reaction of 2-(p-tolyl)pyridine, 4-vinylbenzoic acid, and iridium trichloride hydrate. The complex was characterized by elemental analysis, FTIR, and ^1H NMR. The UV-vis absorption and photoluminescence of the complex were investigated. The complex shows strong ^1MLCT (singlet metal to ligand charge-transfer) and 3MLCT (triplet metal to ligand charge-ransfer) absorption at 400 and 450nm, respectively. It also shows a strong photoluminescence at 523nm in dichloromethane. These results suggest the complex to be a promising phosphorescent material.
