Photoinduced electron transfer reactions in zeolite cages. Progress report, January 15, 1990--August 1, 1992

摘要

This report summarizes work in the two areas of zeolites and layered double hydroxides. Results of studies on structural aspects of Ru(bpy)(sub 3)(sup 2+)-zeolite Y are summarized. Photoinduced electron transfer between entrapped Ru(bpy)(sub 3)(sup 2+) and methylviologen (MV) in neighboring supercages was examined. Benzylviologen was also used. Since molecules larger than 13 (angstrom) cannot be accomodated in zeolite cages, the layered double metal hydroxides (LDH) LiAl(sub 2)(OH)(sub 6)(sup +)X(sup (minus)) is being investigated. Organized assemblies of hydrophobic domains are made by introducing into the interlayer long-chain carboxylic acids R(CH(sub 2))(sub n)COOH. Zinc tetraphenylporphyrin sulfonate (ZnTPPS) is introduced into myristate-LiAl-LDH; photolysis of ZnTPPS-AiAl-LDH with MV(sup 2+) in solution was examined.
