Molecular Devices based on LB Film Techniques

Light-energy Conversion

Abstract

Langmuir-Blodjett (LB) films are now attracting much interest because of their high potentiality as molecular devices and as useful parts of electronic devices. This article reviews attempts to construct functionalized LB films for light-energy conversion : dry-type as well as wet-type solar cells; light-driven molecular pumps; molecular wires and light-harvesting systems. Preparation and characterization of LB films, including an application of a scanning electron microscope for mixed LB monolayers, are explained also.
