ABSTRACT:
The present invention concerns the fields of processes for producing an organic ultrathin film having polyacetylene linkages and the resultant films. In one embodiment the process for producing the film consists of the steps forming an acetylene monomolecular film on a water surface, applying magnetic or electric field to enhance orientation, irradiating the acetylene film with an energy beam to polymerize the acetylene film into a polyacetylene film. Other embodiments for producing the film consists of the steps of forming an acetylene film by chemical absorption, applying magnetic or electric field, and irradiating the film with an energy beam. The polymerized film is useful as an electrical material having high conductivity and as an optical material having non-linear effect.
