| Luminescence, Stacking Effects and Axial Coordination of Aluminum and Gallium corroles | |
| 摘要: 本文合成了2种第三主族金属铝和镓咔咯配合物Al(tpfc)、Ga(tpfc)、Al(tpfc)(Py)2、Ga(tpfc)(Py)。测定了在甲苯溶液中，铝和镓咔咯的电子光谱、荧光光谱、荧光量子产率及荧光寿命。在不同溶剂作用下，铝和镓咔咯的电子吸收光谱和荧光光谱的峰位置和强度存在差异。在二氯甲烷溶液中，轴向配体吡啶能促进铝和镓咔咯的π-π堆积。不同轴向配体与金属咔咯的结合能力为：咪唑>4-甲基咪唑>吡啶，铝比镓的咔咯配合物有更强的结合轴向配体的能力。 | |

| Abstract: Two metallocorroles of the third main group metal [(Al(tpfc), Ga(tpfc), Al(tpfc)(Py)2 and Ga(tpfc)(Py)] were prepared. The electron absorption spectra, emission spectra, fluorescence quantum yield and lifetime of these aluminum and gallium corroles had been investigated in toluene solution. The electron absorption spectra and fluorescence spectra of aluminum and gallium corroles showed difference in peak position and intensity in different solvents. In dichloromethane, axial ligand pyridine could promote the π-π stacking of aluminum and gallium corroles. The intereactions of 1-Al and 2-Ga with different axial ligand followed the order: imidazole>4-methylimidazole>pyridine. Aluminum corrole has stronger binding ability with axial ligand than gallium corrole. | |
