摘要
以4-(2-吡啶基)-苯甲醛(fppy)和2-苯基吡啶(ppy)为配体合成了一个中性金属铱(Ⅲ)配合物Ir(ppy)_2(fppy),通过单晶X-射线衍射分析法测定了晶体结构,并通过元素分析、质谱、核磁等表征手段对配合物进行了结构表征。研究了室温下配合物的紫外-可见吸收光谱,荧光发射光谱及寿命等光物理性质,此外还利用循环伏安法对配合物的电化学性质进行了研究。
One neutral iridium (Ⅲ) complex Ir (ppy) 2 (fPPY) ( PPY = 2-phenylpyridine, fppy = 4- (2-pyridinyl) benzaldehyde) was synthesized, and the structure was characterized by single crystal X- ray diffraction analysis as well as EA, MS and NMR. The photophysical property of the complex was studied by UV-visible absorption spectroscopy, fluorescence emission spectroscopy and the fluorescence lifetime both in solid state and solution at room temperature. In addition, the electrochemical property of the complex was studied by cyclic voltammetry.
