Synthesis and characterization of transparent phenothiazine-based polymers via buchwald-hartwig polymerization as promising functional organic materials

A novel series of polymers incorporating 10-hexyl-10H-phenothiazine and substituted anilines were synthesized through Buchwald-Hartwig amination polymerization. Comprehensive characterization of the polymers by Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA showed remarkable thermal stability. Size Exclusion Chromatography (SEC) measurements indicated low polydispersity, and average molecular weights, both conducive to film formation. Optical characterization, conducted through UV-vis absorption spectroscopy, highlighted the transparency of the synthesized polymers in the visible region. Additionally, band gap was estimated by the intersection point of absorption and emission spectra. This multifaceted analysis contributes valuable insights into the structural and optical properties of the developed polymeric compounds, demonstrating their potential applications in various fields.
