摘要：

We have studied the influence of different solvents and of the pH on the spectroscopic properties of Sn(IV)tetrapyridyl and tetramethylpyridinium porphyrins. Then these porphyrins were immobilized in sol-gel matrices. The spectroscopic properties of the immobilized porphyrins are dependent on the composition of the matrix and on its polarity. Evidence for the presence of a distribution of environments for the porphyrin in the matrix are demonstrated using fluorescence spectroscopy and maximum entropy method (MEM).
