Abstract

Abstract The present invention relates to an electric material, and particularly it relates to an organic substance having a polyacetylene linkage which exhibits electrical conductivity and nonlinear optical effect. More particularly, the present invention provides a process for producing an organic substance having a polyacetylene linkage which can be utilized, for example, as an electric material, said process comprising immersing a substrate having a hydrophilic surface in a solution of a substance containing an acetylene (--C.tbd.C--) group and a chlorosilane (--SiCl 3 ) group dissolved in a nonaqueous organic solvent, thereby subjecting the substance containing an acetylene group and a chlorosilane group to chemical adsorption on the surface of the substrate, subjecting said substance to polymerization reaction by the use of radiation such as X-rays, electron beams, γ-rays, or the like, and thereby producing a polyacetylene.
