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 pi-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 x 10(-8) and 4 x 10(-6) S cm(-1).
