Abstract

The reaction of 1,2-diamino-4-arylimidazoles with isatin and N-methylisatin, as a result of which the corresponding imidazo[1′,2′:2,3]-1,2,4-triazino[6,5-b]indoles were obtained, was studied. The corresponding Schiff base was also isolated in the case of the reaction of 1,2-diamino-4-(p-tert-butylphenylene)imidazole with N-methylisatin. The electronic and IR spectra of the synthesized compounds were studied. The possibility of the use of the degree of orderliness of the synthesized compounds in a liquid-crystal matrix as an additional spectral method in proving the structures of the compounds is demonstrated.
