Responsive Gels with the Polymer Containing Alternating Naphthalene Diimide and Fluorinated Alkyl Chains: Gel Formation and Responsiveness as Well as Electrical Conductivity of Polymer Thin Films
A new electroactive polymer 1 with alternating NDI (naphthalenediimide) moieties and fluorinatedalkylchains was prepared and characterized. Gels of polymer 1 were formed in several solvents. Interestingly, gels of polymer 1 exhibited responsiveness toward N2H4, F− and CN−. Absorption and ESR spectroscopic studies revealed that such responsiveness is owing to the reduction of NDI moieties into the
