Through Knoevenagel synthesis of coumarines to methcrylate monomers containing optical active groups

Coumarines are compounds originating from the nature, used in many areas such as cosmetics, seasonings, pharmaceutics, and photochemistry. There are many developed methods of coumarines synthesis, e.g. Pechman reaction, Perkin reaction, Knoevenagel condensation and many others. Since coumarine derivatives have been studied in our laboratory, we have investigated their synthesis through Knoevenagel condensation. 3-carboxycoumarines were synthesized from appropriate hydroxybenzealdehydes and then their methacrylate monomers were synthetised using 2-hydroxyethyl methacrylate. All compounds were identified by GC-MS and IR and gave satisfactory results in comparison with authentic samples. Described in this paper series of monomers were copolymerised with other monomers to give photo- and electroluminescent copolymers.
