Copolymerization of EDOT and BTPA was carried out using FeCl3 as an oxidant. The best polymerization results, i.e., high yield with negligible insoluble portion was obtained when oxidant/monomer = 2, at 20 ºC using nitrobenzene as a solvent. The obtained copolymer was soluble in common organic solvent such as toluene, chloroform, and THF. The polymer showed absorption maximum around 460 nm. Polymer had oxidation peak around 1.0 V versus Ag/AgCl electrode. Hole mobility of the copolymer containing 57 % of EDOT unit showed highest mobility of 3×10-5 cm2/V•s.
