Controlling Molecular Ordering in Aqueous Conducting Polymers Using Ionic Liquids

The molecular ordering of aqueous conducting polymers is controlled using a rational method. By introducing various ionic liquids, which have designed electrostatic interactions to PEDOT:PSS solutions, the evolution of the molecular ordering of the PEDOT is manipulated. Consequently, highly ordered nanostructures are achieved with a reduced π–π stacking distance of ≈3.38 Å and, thus, a maximum σ_dc of ≈2100 S cm^–1.
