ABSTRACT:
This invention relates to production of a super long conjugated polymer to be used for a molecular device, etc. According to this invention, an acetylene derivative is previously oriented and formed into a monomolecular film on the surface of a substrate and its acetylenic group is polymerized by a catalyst or by irradiation of an energy beam while keeping the orientation. Since the respective molecules are oriented and aligned on the substrate surface, the polymerization reaction readily proceeds, and after the polymerization the resulting polyacetylene molecules are prevented from the breakage of conjugated bonds caused by thermal agitation or twisting of the polyacetylene molecules. Accordingly, a polyacetylene or polyacene type polymer having long conjugated bonds can be obtained easily.
