Abstract
By condensation of the perchlorates of N-phenyl-2-(β-acetanilidovinyl)quinaldine (I) and N-phenylquinaldine (III) with aromatic amines (o-, m-, p-phenylene diamine, benzidine, o-tolidine, dianisidine, 4,4′-azoaniline, aminoazobenzene, and aniline) symmetrical and asymmetrical quinohemicyanines not previously described in the literature were synthesized and their absorption spectra in the visible region were determined.
