The incorporation of semiconducting materials into conjugated polymers improves the properties of optoelectronic devices. In this study, polycarbazole-zinc sulfide (PCZ) composites were synthesized and thin films were produced. The addition of zinc sulfide enhanced charge transfer qualities, resulting in better photophysical and electrical characteristics.
The incorporation of semiconducting materials into the pi-conjugate polymer improves the optical, thermal, electrical, and electrochemical properties of optoelectronic devices. In this study, polycarbazole-zinc sulfide (PCZ) composites are synthesized via an in situ polymerization process, and their thin films are produced by spin coating. ZnS enhances the charge transfer qualities of polycarbazoles, which in turn results in better photophysical and electrical characteristics. The PCZ15 thin film has an optical band gap of 2.44 eV, a refractive index of 2.15, and an Urbach energy of 0.44 eV. Relative quantum yield for the PCZ15 was 38.4%, while F & ouml;rster resonance energy transfer efficiency was 2%. Excellent thermal performance was shown by the PCZ15, which was 37.04% more efficient than the pure polycarbazole with an activation energy of 356 kJ/mol. PCZ15 has an outstanding charge mobility of 54.22 m(2)/(V s) and a conductivity of 0.298 S/cm. High charge transfer efficiencies were discovered by electrochemical analysis, which had a specific capacitance of 116 Fg(-1). These characteristics strongly supported the viability of the PCZ15 thin film as a high-performance polymer-derived composite materials for optoelectronic devices.
