| Abstract: | The 13C NMR spectrum analysis of electrochemically prepared poly(3-methylthienylene) films has been investigated. Both a film doped with ClO4 ions (P3MT-ClO4) and an undoped film (P3MT0) give only two distinct absorption bands through the electrochemical reduction of P3MT-ClO4. These distinct bands are definitely attributable to the methyl group (upper field) and the thiophene ring (lower field), respectively, and are characteristic of well-defined poly(3-methylthienylene). The correlation between conductivity and 13C NMR spectra will be discussed. |
