Study of Photochromism in Benzenesulphonylhydrazones

Photochromic behaviour of benzenesulphonylhydrazone derivatives has been investigated in crystalline state, ethanol-ether (2:1) and PMMA matrix at liquid air temperature (-180 deg C).Benzenesulphonylhydrazones containing ortho-hydroxy group in the aldehydic ring showed reversible colour change on irradiation (365 nm) in solid state and rigid matrices in liquid air temperature.Whereas the presence of electron-withdrawing groups at C5-position in the salicylidene ring affected the formation of photo-coloured product.Hydrazones of o-nitrobenzaldehyde did not show photochromic change and irreversible spectra were obtained on irradiation of their methanolic solution at room temperature.
