A novel poly(aryleneethynylene) with tetrathiafulvalene (TTF) side chains: Synthesis, self-assembly, and electroactive property

Abstract

A novel poly(aryleneethynylene), in which the main chain and the tetrathiafulvalene (TTF) side chains are coplanar, has been prepared and characterized. The polymer can self-assemble in tetrahydrofuran (THF) and the n-extended coplanar backbones adopt good face-to-face stacking, which is confirmed by X-ray diffraction (XRD) analysis. Cyclic voltammetry has revealed that the polymer has reversible electroactive properties. The optical bandgap deduced by UV-vis absorption spectroscopy and the electrochemical bandgap are 2.03 and 2.14 eV. The conductivities of the powder and the realigning solid of the polymer are 6 × 10-8 and 4 × 10-6 S cm-1. © 2008 WILEY-VCH Verlag GmbH & Co. KGaA.
