Polyacrylates with high refractive index have been widely applied in optical film,liquid crystal display,and LED enhancement film and so on.In order to synthesize the monomers with high refractive index and low dispersion,five thiazole and triazole compounds were synthesized by introducing sulfur atom and aryl with high molar refractivity and using five-membered aromatic heterocyclic group as center,ethoxy as flexible chain,and acrylate as ended group.The structures of these compounds were confirmed by IR,^1H NMR,^13C NMR and MS,and their Abbe numbers and refractive indexes were measured by Ab...
