A method for depositing an electrically conducting film on an electrode and the film resulting from that method. An electrically conducting film according to the present invention is deposited by immersing the electrode in a solution of a precursor polymer in a predetermined solvent. The precursor polymer includes a plurality of electrochemical polymerizable monomers. Each monomer has first and second polymer-forming active sites that can be joined by electrochemical polymerization and third and fourth polymer-forming active sites that can be joined chemically in solution. The precursor polymer is constructed from the monomers joined by the third and fourth polymer-forming active sites. The precursor polymer is soluble in the solvent whereas a polymer formed by electrochemical polymerization of the first and second polymer-forming active sites is insoluble in the solvent. An electrical potential is applied to the electrode to cause monomers of the precursor polymer molecules to be joined electrochemically by their first and second polymer-forming active sites. Precursor polymers may be constructed from monomers such as fluorene, triophene, pyrrol, biphenyl, poly(vinyl carbazole) or poly (vinyl oxy thiophene). The solution may also include non-polymerized monomers or other compounds that can be electrochemically linked to the first and second polymer-forming active sites of the monomers. These monomeric units are joined to the first and polymer-forming active sites of the monomers in the precursor polymers, and to each other, during the electrochemical polymerization thereby forming chains of the monomeric units that are linked to the precursor polymers by the first or second polymer-forming active sites of the monomers in the precursor polymers.
