Chromophoric Carbazole Methacrylates as Intermediates for Photorefractive Applications

Methacrylate monomers containing a carbazole fragment and a chromophoric azophenyl sulfonyl group were synthesized, being characterized as definite chemical species and as potential intermediates for photorefractive applications. Quantum chemical calculations were carried out to get values of dipole moments, polarizabilities and hyperpolarizabilities. These values were used to calculate figure of merit (FOM) of the monomers, which indicated a contribution of linear and nonlinear optical effects to photorefractive phenomena. It was found that in the monomers in question the linear optical effect contribution prevailed over nonlinear one.
