Abstract
Symmetrical pentamethine, heptamethine or nonamethine cyanine dyes substituted in the central methine group of the cyanine chain by a cyano group are produced by condensing one molecular equivalent of cyanacetic acid with at least two molecular equivalents of an alkyl or aralkyl quaternary salt of a 5- or 6-membered heterocyclic N compound having in the a - or g -position to the quaternary N atom an alkyl, aralkyl or aryl thioethervinyl, thioetherbutadienyl, selenoethervinyl or selenoetherbutadienyl group or a group of formula -(CH=CH)mNH2 (wherein m is 1, 2 or 3) or the N-acyl, N-aryl or N-acylaryl derivatives thereof. Bis - 2 - (3 - Methylbenzthiazole) - g - cyano - pentamethinecyanine p-toluenesulphonate is prepared by heating together 2-(b -ethylthiovinyl)-benzthiazole metho-p-toluenesulphonate, cyanacetic acid and pyridine. Bis-2-(1 : 3 : 3-trimethylindolenine) - g - cyanopentamethinecyanine iodide and bis-2-(1-ethylquinoline)-g -cyanopentamethinecyanine iodide are similarly prepared and bis-2-(3-ethylbenzthiazole)-g -cyanopentamethinecyanine iodide is similarly prepared from 2-(b -acetanilidovinyl)-benzthiazole ethiodide.
