摘要
本文将ｍｅｓｏ－苯基四苯并卟啉锌（Ｚｎ－Ｐ_ｎＴＢＰｎ＝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（Ｈ_２Ｐ_ｎＴＢＰｎ＝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。
In this paper,the preparation of meso-phenyl substituted tetrabenzoporphyrins (H_2-P_nTBP n=1～4)were performed by the demetalation of the corresponding Zn-P_nTBP 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-P_2TBP and H_2-P_2TBP on the solution concentration was studied.
