摘要:

合成了一系列周边取代的Corrole(1, 2, 3, 4)及其镓配合物1-Ga(Py)、2-Ga(Py)、3-Ga(Py)、4-Ga(Py),通过核磁共振氢谱(1H NMR), 紫外-可见光谱, 电喷雾离子质谱(ESI-MS)的方法对其进行了表征. 研究了不同溶剂对这一系列自由Corrole 及镓Corrole 的紫外-可见(UV-Vis)吸收光谱, 稳态荧光和时间分辨荧光光谱, 将获得的荧光衰减动力学曲线采用单指数拟合并进行解卷积处理获得荧光的寿命值. 非(弱)极性溶剂对镓Corrole 紫外光谱的影响服从Bayliss 方程, 且镓Corrole 非辐射能量损失hc(ν1A-νF)与F(n)呈线性相关.

Abstract:

A series of peripherally substituted free base corroles (1, 2, 3, 4) and their gallium complexes 1-Ga(Py), 2-Ga(Py), 3-Ga(Py), 4-Ga(Py) were synthesized and characterized by proton nuclear magnetic resonance (1H NMR), UV-visible (UV-Vis) spectroscopy and electrospray ionization mass spectra (ESI-MS). The UV-visible spectra, steady state fluorescence spectra,and time resolved fluorescence spectra of the free base corroles and their gallium complexes were recorded in different solvents. Fluorescence lifetimes were obtained by fitting fluorescence decay kinetics curves using a single exponential simulation. The effects of non or weak polar solvents on the UV spectrum of gallium corrole were fitted to the Bayliss equation and the non-radiative energy loss hc(ν1A-νF) of gallium corrole and F(n) showed a linear correlation.

Key words: Corrole, Gallium, Florescence, Solvent effect
