Photosensitive methacrylate monomers, derivatives of azobenzene, were synthesized. The route of syntheses was based on coupling of diazonium salts of sulfathiazole, sulfomethoxazole, sulfadiazine, 4-aminobenzoic acid and 4-nitroaniline with N-alkyl-N- [2-(methacryloyloxy)ethyl]aniline. The trans cis isomerization of the monomers in DMSO solution was investigated by UV-VIS spectroscopy recording their spectra during illumination and thermal recovery periods. It was found that except for nitro derivatives the yield of trans-cis isomerization was ca. 50% and that the reverse reaction was a result of thermal relaxation. The spectroscopic studies were accompanied by quantum chemical calculations.
