摘要：

A series of water soluble viologen-linked trisulfonatophenylporphyrins (TPPSCnV; n = 3-6) were synthesized. Viologen is connected with the trisulfonatophenylporphyrin via a methylene chain (-(CH2)(n)-: n = 3-6) in these compounds. The photochemical and electrochemical properties of TPPSCnV were investigated by using the absorption spectra, the fluorescence spectra and the cyclic voltammetric measurement. The photoexcited singlet state of the porphyrin moiety of TPPSCnV was quenched by the bonded viologen. (C) 1997 Elsevier Science B.V.
