Polymers with benzylidene fragment for nonlinear optical application

Oxazalone and thiohydantoin derivatives were synthesized and their physicochemical properties are determined by absorption, fluorescence, fluorescence excitation and HNMR spectroscopies. The polymerization was carried out in DMF with AIBN as initiator. The products of polymerization were characterized by HNMR. The third order nonlinear optical properties of oxazolone and thiohydantoin containing compounds have been investigated in solutions using degenerate four wave mixing (DFWM) method at 532 nm.
