Electron transfer reactions in zeolites and related solid-state materials are being studied. Some particular areas of study are: Electron transfer reactions of linked sensitizer-acceptor molecules. We have studied via laser flash photolysistransient absorbance the photochemistry of linked Ru(bpy)/sub 3/--diquat molecules exchanged onto the outer surface of zeolite L powder. Electron-donor quenching of excited-state RuL/sub 3/ complexes. We have studied electron transfer reactions between cyanometallate anions M(CN)/sub 8//sup /4 minus//(M = Mo,W), M(CN)/sub 6//sup /4 minus//(M = Fe,Os) and excited state ruthenium complexes. Quantum-size TiO/sub 2/ in zeolite L. We are attempting to prepare systems in which the conduction band of an oxide semiconductor is used to convey electrons from a sensitizer to a catalyst within a zeolite L particle. Internal platinization of pillared clays. We have photoplatinized dispersed Na/sup +/--montmorillonite, using PtCl/sub 6//sup /2 minus//as the platinum source, and then pillared the clay with A1(OH)/sub 2/C1 solutions. We are currently investigating the size and charge selectivity of these catalytic materials.
