Electron transfer in monolayer assemblies

Monolayer assernblies are rigid structures of specifically designed architecture. Processes can be studied depending on the relative position of several molecules which interact with each other to form a cooperative system. Appropriately constructed monolayer assernblies are useful to investigate light induced vectorial charge separation. A number of different arrangements to study electron motions c>re given, such as the transfer of an electron from an excited dye molecule to an acceptor across the hydrocarbon portion of a monolayer, from an electron source to an excited dye molecule, or from an excited dye aggregate to an acceptor. Attempts which have been made to model potential profiles with unsaturated chains are discussed. They are of interest for an efficient charge transfer from an excited dye to an electron acceptor.
