Phtoinduced Electrontransfer in Clay Interlayers

Abstract

Artificial molecular assemblies to modify photosynthesis have been a dreamy target for many scientists. Clay mineral can be a candidate for molecular assembly system to make effective photoelectrontransfer reaction-a basic process of the photpsynthesis. The remarkable characteristics of clay minerals for the photoelectrontransfer can be classified as follows; 1) molecular aggregation in an antiparallel fashion, 2) high polarity to stabilize polar intermediates in photoinduced charge separated state and 3) applicability to many kinds of molecules by adjusting the basal spacing. The layered crystalline structure of clays can also work as a backbone building block in multilayered supramolecular systems.
