چکیده
|
The schiff bases n-(5-phenylthiazole-2-yl)-2-hydroxylnaphthaldehydehydrazone (1),n-(4′-chloro-5-phenylthiazole-2-yl)-2-hydroxylnaphthaldehydehydrazone (2),and n-(4′-nitro-5-phenylthiazole-2-yl)-2-hydroxylnaphthaldehydehydrazone (3) were synthesized. these compounds were characterized by using ir,1h nmr,13c nmr,and ms. the photochromism of the compounds was investigated by ir and uv-visible spectrometry which is time variable under irradiation of 254 nm uv light. the thermochromism of the compounds was studied using temperature-variable ir,uv-visible spectrometry,tg,and differential scanning calorimetry (dsc). the results suggested that compound 2 showed thermochromism properties and compounds 2 and 3 displayed photochromism properties. the relationship between the substituents species and photochromic or thermochromic properties of these compounds was revealed as well. � 2016 shaoping zhu et al.
