Abstract:
A series of π‐conjugated alternating copolymers consisting of Th‐ITN‐Th and p ‐C 6 H 2 (OR) 2 units were synthesized. XRD indicated that the copolymers assume an interdigitation packing mode, and UV‐Vis spectra revealed a strong tendency for self‐assembly. Upon molecular assembly of the copolymer, the UV‐Vis absorption shifted by about 100 nm to a longer wavelength from that of the single molecule. The copolymers underwent electrochemical oxidation (or p‐doping) and reduction (or n‐doping) at 0.2 and −2.0 V versus Ag + /Ag, respectively. A p‐doped copolymer film showed an electrical conductivity of 182 S · cm −1 , and the temperature dependence of electrical conductivity was measured. The copolymer showed piezochromism and served as a p‐channel material for a field‐effect transistor. magnified image
