A process for producing a metallized polyacetylene-type ultralong conjugated polymer comprising immersing a substrate having a hydrophilic surface in a first nonaqueous organic solution containing a compound containing an acetylenic group (--C.tbd.C--) and ##STR1## group (hereinafter referred to as silane-type surfactant) to deposit a chemisorbed layer of the silane-type surfactant on the substrate by chemisorption, immersing the substrate on which the chemisorbed layer is deposited in an aqueous solution containing a metal ion to replace a hydrogen atom connected to the acetylenic group by the metal atom, and immersing the substrate on which the chemisorbed layer is deposited in a second organic solution containing a metal salt catalyst to polymerize the molecules at the acetylenic group in the chemisorbed layer. A process according to the present invention makes it possible to obtain a metallized polyacetylene-type ultralong conjugated polymer which has excellent electrical conductivity and nonlinear optical effects and which is stable. Further, the present invention gives a metallized polyacene-type ultralong conjugated polymer. |
