Electrosynthesis and charge-transport properties of poly(3',4'-ethylenedioxy-2,2':5',2''-terthiophene)
Polythiophene containing 3,4-ethylenedioxythiophene (EDOT), poly(3 ',4 '-ethylenedioxy-2,2 ':5 ',2 ''-terthiophene), was synthesized by electrochemical oxidation of the corresponding monomer, 3 ',4 '-ethylenedioxy-2,2 ':5 ',2 ''-terthiophene, in acetonitrile. The resulting polymer was soluble in DMSO and THF, and was characterized by H-1 NMR and mass spectroscopies, and GPC. The electrical conductivity of the oxidized polymer film was found to be comparable to those for polythiophene and poly(methylthiophene) despite of its short pi-conjugation length.
