水溶性金属卟啉在水溶液中的光物理与光化学研究

The Photophysical and Photochemical Properties of Water-soluble Metalloporphyrins in Aqueous Solution

研究了５种水溶性金属卟啉ＺｎＴＭＡＰＰ、ＺｎＴＭＰｙＰ、ＭｇＴＭＰｙＰ、ＺｎＴＢＰｙＰ和ＺｎＴＴＰＳ４的光物理（吸收光谱和荧光光谱、振子强度、荧光寿命、量子产率）、激发态氧化还原电势及光稳定性。结果表明ＭｇＴＭＰｙＰ是比ＺｎＴＭＰｙＰ更好的光敏剂。

Several photophysical(spectra,oscillator strength,lifetimes,and quantum yields for fluorescence),excited state redox properties and photo-stability of five water-soluble metalloporphyrins(ZnTMAPP,ZnTMPyP,MgTMPyP,ZnTBPyP,and ZnTTPS4 where TMAPP=tetrakis-(trimethylaminophenyl) porphyrin,TMPyP=tetrakis(N-methylpyridyl) porphyrin,TBPyP=tetrakis(N-benzylpyridyl) porphyrin,and TTPS4=tetrakis(3-sulphpotolyl)porphyrin) were investigated.It was found that MgTMPyP is a good photosensitizer compared with others.
