Fifteen new chromophoric chain β-aryl substituted butadienyl-benzothiazole asy-cyanine colorants are synthesized by condensing substituted 3-isopropylbenzothiazolium iodides and 4-dimethylaminostyrylphenyl ketones using alkaline ethanolic DMF solution. The colorants show bathochromic shifts in comparison with unsubstituted analogues and styryl analogues but hypsochromic shifts when compared to 3-m
