New methacrylic monomers, their polymers with benzylidene fragment were synthesized. Structures of all compounds were determined by HNMR, UV- spectroscopies. The third order nonlinear optical properties of oxazolone, thiazolidinone and thiohydantoin containing compounds were investigated in solutions using degenerate four wave mixing (DFWM) method at 532 nm.

Third order nonlinear optical properties of Poly(p-phenylenevinylene) have been investigated at 532 nm using degenerate four wave mixing and Z-scan techniques. Intensity dependent absorption has been attributed to photogenerated gap states arising from one-photon π–π* transition, and the coefficient of nonlinear absorption has been estimated. The observed intensity dependence of the degenerate four wave mixing signal has been explained using four-level model involving gap state transitions.
