| 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(IrCl_3·H_2O)配位,得到了铱配合物单体Ir(ptpy)_2(VBA),再将其与乙烯基咔唑共聚制得了一种含铱配合物的新型聚合物.通过元素分析、FT-IR光谱和~1H NMR谱等对Ir(ptpy)-2(VBA)和聚合物的结构进行了表征.凝胶色谱仪(GPC)测试结果表明,聚合物的数均分子量(Mn)为8230.此外还研究了Ir(ptpy)_2(VBA)和聚合物的紫外-可见(UV-vis)吸收光谱和光致发光(PL)光谱.光致发光光谱测试结果表明,聚合物在固态时,主体咔唑基团向客体铱配合物基团有着较为有效的能量转移.聚合物在501nm处有较强的金属配合物三重态的磷光发射峰,是一种绿色磷光材料.

| Abstract: | A new iridium complex Ir(ptpy)2(VBA) was synthesized by reaction of 2-(p-tolyl)pyridine,4-vinylbenzoic acid,and iridium trichloride hydrate,and then the iridium complex was copolymerized with N-vinyl carbazole to form a polymer. The polymer and iridium complex were characterized by elemental analysis,1H NMR,and FT-IR. By the result of gel permeation chromatography (GPC),the number average molecular weight of the polymer was calculated to be 8230,according to the polystyrene standard calibration curve. Furth... |
