Abstract
Extensive triplet state spectroscopic investigations were carried out with a series of 5,10,15,20-tetrakis(methoxyphenyl)porphyrins, Triplet absorption spectra, triplet lifetime, triplet quantum yield and quant um yield for singlet oxygen production were determined with different absorption and emission techniques, using the frequency-doubled beam o f a Nd:YAG laser, It has been found that these synthetic porphyrins ar e effective photosensitizers which can be used as model compounds to i nvestigate the theoretical and instrumental aspects of PDT.
