SYNTHETIC MOLECULAR ORGANIZATES

Organized systems of molecules (organizates) can be obtained by assembling monolayers of planned composition and architecture. Appropriately constructed mololayer assemblies can be used to study light-induced vectorial charge separation. Such systems are of interest in designing devices for solar energy conversion. Possibilities of such devices are discussed and experiments are presented to demonstrate light-induced charge separation. Charge separation is limited by the quantum mechanical tunnelling effect which cannot be avoided at molecular dimensions. Experiments to study that effect are described. Monolayer assemblies to discriminate between different mechanisms of spectral sensitization of photoeffects by dyes are discussed and cases are considered where an increased spectral sensitization is achieved by cooperation of different dye molecules. © 1979.
