Here we report on the induction of orientation of rod-like semiconducting molecules by depositing them on the surface of conjugated polymers thin films prepared by friction transfer method. We also discuss about induction of orientation of multilayers and mixed films of p-type and n-type semiconducting molecules. It was found that when pentacene thin films were deposited on the friction-transferred films of polythiophene, the long axis of pentacene was oriented in parallel to the polythiophene backbone direction. Photo-electric conversion devices prepared with the oriented pentacene films showed higher conversion efficiency than those prepared with pentacene whose orientation was not controlled. For p/n strucures, we prepared 2 types films of -sexithiophene and perfluoro-sexithiophene sequentially deposited and co-deposited on the friction-transferred polythiophene films, and both structures showed good orientations. |
