Control of chiral ordering in aggregated poly[3-(S)-[2-methylbutyl]thiophene] by a doping-dedoping process.

摘要: The chiral ordering in aggregated poly(3-alkylthiophene) can be controlled by a metal salt-dependent doping-dedoping process. Enhancement or reduction the anisotropy factor depends on doping level, such that driven polymer-metal salt interactions, and dedoping aggregate formation must balanced order to achieve maximal ordering. This phenomenon provides new basis control arrangement conjugated polymer aggregates, relying solely doping, thus avoiding tedious modification of side-chain main-chain structures.
