Abstract:Meso-tetra (p-carboxyphenyl)porphine was prepared and the tin-complex was immobilized into poly (styrene) beads. The obtained polymer-supported complex showed an electron transfer ability similar to that of non-supported native complex. As applying this electron transfer function of both complexes for a photoinduced hydrogen evolution system, hydrogen was generated in the presence of electron donor and Pt catalyst. This result indicated that both polymer-supported and non-supported complexes worked as not only an electron carrier but also a photosensitizer. However, the immobilization of the complex onto the polymer lowered the electron transfer ability.
