Abstract
Change transfer complex of 4-cyano-5,6-diphenylpyridazine-3(2)selenone (CDS) was obtained by reacting of CDS with picric acid. The structure was confirmed by a number of spectral (IR, Raman, UV-Vis) methods. The activation parameters Delta E, Delta H, Delta S, and Delta G were obtained from the DTG diagrams using Coats-Redfern and Horowitz-Metzger methods. The photostability of 4-cyano-5,6-diphenylpyridazine-3(2)selenone (CDS) and its charge-transfer complex doped in polymethyl methacrylate(PMMA) matrix exposed to UV-Vis radiation was studied.
