Synthesis, structure, and UV-VIS absorption spectra of azo dyes derived from (dialkylamino)thiazole dimers

(Dialkylamino)thiazole dimers act as very strong electron-donating coupling components in azo dyes, the first and second UV-VIS absorption bands of which were observed at λ = 568-737 (ε = 24000-88000) and 404-475 (ε = 9200-52000) nm in dichloromethane, respectively. The azo compounds derived from the (dialkylamino)thiazole dimers having very strong electron-withdrawing moieties such as 4-(perfluoroalkylsulfonyl)phenyls, 2,4-dinitrophenyl, and thiazol-2-yls exhibited a negative solvatochromism. This is the first example of a negative solvatochromism in neutral azo dyes.
