Abstract
Photo-energy conversion is very important not only as a source of new clean energy, but also as a means of information processing. Several attempts were made to improve the efficiency of photoinduced charge separation by using interfacial electric fields of micelles and bilayer membranes, a good electron mediator, electron exchange reactions between redox chromophores aligned in molecular assemblies in aqueous solutions. Langmuir-Blodgett films have been employed to achieve unique properties such as amplified fluorescence quenching, anisotropic and molecularly controlled photoconduction. Photoresponsive thin solid films have been employed to achieve photon-mode super-resolution based on transient bleaching, ultrafast color changes due to photoinduced electron transfer reaction in ion-pair charge transfer complexes, ultrafast optical parallel processing based on complex refractive index changes in guided wave geometry consisted of a thin metal film and a thin polymer film containing organic dyes.
