摘要
利用荧光手段对自制的3种卟啉蒽醌化合物及其锌配合物与母体卟啉进行了研究,计算了各种化合物单重激发态的能量Es、荧光量子产率及荧光猝灭百分率.从荧光猝灭的角度证明它们确实能在光激发下进行分子内电子转移,形成分子内电荷分离态.同时探讨了有机碱的轴向配位及溶剂对PAQ化合物荧光性质的影响.
In this paper, the fluorescence spectra of porphyrinanthraquinone, porphyrin-an-thraquinone Zn(Ⅱ), and parent porphyrin were studied by means of fluorescence. The ener-gy of singlet excited state(Es), fluorescence quantum yield and quench percentage were esti-mated. It is demonstrated by the data of fluorescence quench that the intramolecular electron transfer, which leads to the formation of intramolecular electric charge separating-state, oc-curred under excitation of light indeed. In the meantime, the effects of axial coordination and solvent on fluorescence property of PAQ compounds were studied.
