Regioregular poly[3-(4-alkoxyphenyl)thiophene]s: Evidence for a two-step aggregation process
A chiral, regioregular poly[3-(4-alkoxyphenyl) thiophene] has been prepared and studied. Films prepared by fast evaporation of the solvent, consist of random-coils, while films prepared by slow evaporation are composed of chirally aggregated, coplanar strands. Heat treatment transforms the random-coils into aggregated, films via an intermediate state, which was characterized as chiral, coplanar, unaggregated polymer strands.
