Click-modification of a functionalized poly(3,4-ethylenedioxythiophene) (PEDOT) soluble in organic solventsElectronic supplementary information (ESI) available: Chemicals, IR-spectra, and CV. See DOI: 10.1039/c2cc17374c

A PEDOT-based conductive copolymer soluble in organic solvents was synthesized electrochemically using dihexyl-EDOT and azidomethyl-EDOT as monomers and was successfully post-functionalized by click-cycloaddition reaction with a functionalized terminal alkyne under mild heterogeneous conditions. Formation of a PEDOT copolymer soluble in organic solvents has been achieved by electrochemical copolymerization of monomers. In a post-functionalization step, facile immobilization of electron-accepting phthalimide was achieved by click-reaction with high conversion efficiencies.
