| Abstract: | 2-Methyleneindolines containing benzazole residues at the 5-position were synthesized and polymethine dyes were obtained from them. The bathochromic shifts induced by the introduction of heterocyclic residues into indocyanines exceed the similar shifts induced by the same heterocycles in thio and quinocyanines.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1050–1054, August, 1990. |
