Cyanine dyes

Communication 2. Unsymmetrical carbocyanines from derivatives of N-arylquinaldine and of benzthiazole

Summary

  1. 1.

    Nine new quinothiacarbocyanines have been preprared containing aryl radicals on the hetero nitrogen of quinoline.

  2. 2.

    It has been shown that replacement of ethyl on the hetero nitrogen atom by phenyl or naphthyl leads to a slight bathochromic shift in the absorption maximum of the dye.

  3. 3.

    The absorption maxima of the quinothiacarbocyanines obtained may be derived by an additive relationship from those of the corresponding symmetrical dyes, but the intensity of the absorption is reduced in comparison with that of the corresponding symmetrical dyes.
