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

Abstract

Abstract: 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 MgTMPyPis a good photosensitizer compared with others.

Key words: Water-soluble metalloporphyrin, Photophysics, Photochemistry, Photosensitizer
