Functional Polymer Material with Efficient Optical Tunability

The solvent dependent investigation for the bathochromic emission has an extensive report whereas the report on solvent independent material is limited. With approach for invention of photoluminescent material, the hydrothiolation was invoked for the growth of thermally clicked energy tuneable crosslinked photoluminescent polymeric materials. The observed CIE co-ordinates for the crosslinked polymers were Poly-BnNpAll (0.31, 0.48) and Poly-BnNpAlk (0.34, 0.51). The respective quantum efficiency (& phi;) for Poly-BnNpAll and Poly-BnNpAlk were 9.73 % and 6.14 %. The energy tunability and optical responses were validated through DFT calculations and fluorescence Mueller matrix (FLMM) analysis. From FLMM, the optical parameters - fluorescence diattenuation and fluorescence polarizance revealed the excited molecular orientation is more organized relative to ground state. Such materials have scope for application as promoter during photocatalysis, chemosensing, etc.
