摘要: 本文将meso-苯基四苯并卟啉锌(Zn-PnTBP n=1~4)在酸性条件下脱锌,获得了不含金属离子的meso-苯基四苯并卟啉(H2PnTBP n=1~4)。研究了它们的吸收光谱、荧光光谱及在溶液状态下的瞬态光谱特性,并对照相应的锌卟啉,讨论了两者之间的光谱差异。

Abstract: In this paper,the preparation of meso-phenyl substituted tetrabenzoporphyrins (H2-PnTBP n=1~4)were performed by the demetalation of the corresponding Zn-PnTBP in acid conditions.The behaviors of absorption,fluorescence and triplettriplet(T-T)absorp tion spectra were studied,and their fluorescence quantum yields,excited singlet-state and excited triplet-state lifetimes were measured. In addition,the dependence of fluorescence quenching of Zn-P2TBP and H2-P2TBP on the solution concentration was studied.

Key words: meso-phenyl tetrabenzoporphyrins, absorption spectra, fluorescence spectrum, fluorescence quenching
