SYNTHESES AND PROPERTIES OF MICRO-HETEROLAYERS OF CONDUCTING POLYMERS

A novel potential programmed electropolymerization method which enable s us to fabricate any microscopic depth structures in conducting polym er ultrathin films, such as heterolayers and sloped layers, have been developed. The depth profiles of the heterolayers such as thickness an d polymer composition are controlled by applied electrode potential, a nd a nanometer order layered structure has been easily synthesized. Th e aim of the present study is to manipulate electric, optical and the other various properties specific to the depth structure by changing s tructural parameters such as polymer composition or doping level of th e layers, finally to realize an organic superlattice. This paper deals with the preparation of any microscopic depth structures of conductin g polymers such as type I and type II heterostructures Esaki et al pro posed1) as superlattice, by the present potential programmed electropo lymerization method, and the structure-specific properties, including a quantum size effect.
