Modified Bu-PPQ was prepared by in situ chemical oxidative method of polymerization by carrying out simultaneous doping during the polymerization. The rare earth metal series salts i.e., CeCl3 and LaCl3 and Xanthene dyes such as fluorescein and Rhodamine –B at various concentrations are used as dopants. Thin films of the materials were prepared by bath deposition technique. All the PPQ derivative materials formed were investigated though FTIR, NMR spectroscopic and Mass spectrometric analysis. The thermal properties of the materials were studied by TG and DT analysis. Morphological studies of the materials were carried out through XRD, AFM and SEM studies and material is further subjected to electrical characterization by DC- conductivity measurement using four probe conductivity instrument. The optical investigations, providing the temperature-dependent conductive defects formation in the obtained structures. |
