A polyacetylene derivative monolayer was investigated for application as a molecular wire. First, an acetylene derivative monolayer was prepared by chemically adsorbing (self-assembling) 19-trimethylsilyl-18-nonadecynyl-trichlorosilane on a silica substrate. Then, the monolayer was polymerized in the presence of Ziegler-Natta catalyst of triethyl aluminum and tetra-n-butoxy titanium. The polyacetylene derivative monolayer thus synthesized was covalently bonded to the silica substrate and showed conductivity as high as 1×10^<-4> S/cm after being doped with iodine. The method of preparing a conductive polymer monolayer by combination of chemical adsorption and catalytic polymerization leads to a molecular wire which is one of the key technologies for molecular devices.
