The mutual influence of the chromophores of two cyanine dyes connected through a benzene nucleus

  • A. I. Kiprianov

Three isomeric biscyanine dyes have been synthesized, each of which forms a pair of indothiazolocarbocyanines attached to a p-phenylene group through the 4,4′ (I), 5, 5′ (II), and 3, 3′ (III) positions of the thiazole nuclei. It has been found that in the biscyanines II and III the polymethine chromophores are conjugated and influence one another, which is shown by the splitting of the absorption bands of these dyes. In the biscyanines I, no interaction of the chromophores is observed.
