It is an object to provide a conductive organic thin film having organic molecules that include at one end a terminal bonding group that is covalently bonded to a substrate surface, a conjugate bonding group that is located at any portion of the organic molecules and that is polymerized with other molecules, and a polar functional group that does not include active hydrogen and that is located at any portion between the terminal bonding group and the conjugate bonding group, wherein the organic molecules are oriented and their conjugate bonding groups are polymerized, forming a conduction network. The conductivity (ρ) of the conductive organic thin film at room temperature (25°C) is at least 5.5 × 105 S/cm, and preferably at least 1×( 107 S/cm, without dopants, having significantly higher conductivity than metals such as gold and silver. In particular, a film of polypyrrole or polythienylene conjugate bonds that is polymerized through polymerization through electrolytic oxidation has high conductivity.
目的是提供一种导电有机薄膜,其有机分子的一端包括与基底表面共价键合的末端键合基团、位于有机分子任意部分并与其他分子聚合的共轭键合基团,以及位于末端键合基团和共轭键合基团之间任意部分的不包括活性氢的极性官能团,其中有机分子定向,其共轭键合基团聚合,形成传导网络。导电有机薄膜在室温(25℃)下的电导率(ρ)至少为 5.5 × 105 S/cm,最好至少为 1×( 107 S/cm,不含掺杂剂,其电导率明显高于金和银等金属。特别是通过电解氧化聚合而成的聚吡咯或聚噻吩共轭键薄膜具有很高的导电性。
