Preparation, Characterization and Optical Property of Chitosan-Phenothiazine Derivative by Microwave Assisted Synthesis

Abstract In this article, we have described microwave assisted synthesis of 3-formyl-10H phenothiazine and preparation of chitosan-phenothiazine derivative film with potential for optical properties in biomedical applications, vis-à-vis it is also important to ensure that chemical processes used in converting biopolymer to useful material through green chemistry approach. From optical properties and biomedical application point of views, it is a benign technique. Chitosan-derivative film was prepared from hydrogel by solution casting method. The prepared chitosan-phenothiazine derivative was confirmed by Fourier transform infrared spectroscopy (FTIR). The film was evaluated by XRD, thermal analysis, surface morphology, photoluminescence (PL) spectrscopy and second harmonic generation (SHG) study. Overall, the chitosan-phenothiazine derivative film opens new perspectives to optical material for biomedical applications.
