الوصف: Poly(3-thiopheneacetate)/dialkyldimethylammonium complexes (PTA-Cn) were prepared by mixing regiorandom poly(3-thiopheneacetic acid) with dialkyldimethylammonium bromide to study the effect of their self-assembled structures on the optical properties. The lengths of the alkyl groups in the ammonium salts were varied from decyl (C10) to octadecyl (C18) groups. These complexes showed fully developed layer structures with ordered mesophases. PTA-C16 and PTA-C18 with longer alkyl groups showed side-chain crystalline phases, and PTA-C10, PTA-C12, and PTA-C14 with shorter alkyl groups showed side-chain crystalline and liquid crystalline phases at room temperature. When PTA-C18 was heated, a melting transition from side-chain crystalline to smectic liquid crystalline phase was observed at 41.5 °C. The maximum absorption and emission wavelengths of these complexes increased with increasing alkyl chain length indicating that the π-conjugated structure of the regiorandom thiophene backbone changes according to the alkyl groups.
