Abstract:With the scope of bischalcone-based copolyesters can be used as semiconductors; two copolyesters were synthesized by the solution polycondensation method. The Bischalcone diol was analyzed by UV-Visible, FTIR, NMR (1H, 13C NMR) spectroscopy. Using the UV-Visible data, the bandgap energy of the Bischalcone diol was calculated and found to be 2.82 eV. The Physico-chemical properties like Inherent viscosity and refractive index of the copolyesters were determined. Spectral studies such as FTIR, 1H and 13C NMR spe… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
