Abstract
Abstract The present invention relates to electrical and optical materials, and particularly to organic electro-conductive thin films exhibiting electro-conductivity and non-linear optical effect, and to process for the production thereof. Further, the above properties and effects depend predominantly on the orientation of moelcules constituting the films, and therefore the present invention is for control of the orientation.
