Abstract

An electroconductive carboxylic acid functionalized monomer corresponding to Formula (I), wherein A represents a hydrogen or a carboxyl group. Polymerized monomers of Formula (I) conjugated with a biomolecule result in conjugated PEDOT polymers of Formula (III) wherein A is a hydrogen or a carboxylic acid group and B is a biomolecule selected from the group consisting of a peptide, a protein, a lipid, a carbohydrate and a polynucleotide. The biomolecule conjugated polymers can be disposed onto an electrically conductive substrate wherein the substrate has a first layer of PEDOT polymerized on a surface of the substrate and a second layer of biomolecule conjugated PEDOT polymer of Formula (III) polymerized on the first layer of PEDOT. The first and second layers form a charge transport material in electrical communication with the conductive substrate. The electrically conductive substrate further comprises a dopant.
