Abstract

A series of conducting polymer complexes of poly(3-octylthiophene) and titanium dioxide (POT/TiO2) in different proportions were synthesized. X-ray diffraction patterns (XRD) indicated that the interplaner spacing of the composite samples is smaller than the pure TiO2. X-ray photoelectron spectroscopy (XPS) and IR support a chemical interaction between POT and nano-TiO2 in the complexes. Cyclic voltammetry (CV) showed that the energy gap of the POT/TiO2 composite was 0.43 eV, which was smallest when the proportion was 1:1. Ultraviolet–visible spectra (UV–vis) and luminescence spectra (FL) showed that optical performance was far superior to both POT and TiO2.
