Synthesis and optical properties of 6-alkylamino-2-amino-4-(4-(dimethylamino)phenyl)pyridine-3,5-dicarbonitriles

6-Alkylamino-2-amino-4-(4-(dimethylamino)phenyl)pyridine-3,5-dicarbonitriles were obtained by the reaction of primary and secondary amines with 2-amino-6-chloro-4-(4-(dimethylamino)phenyl)pyridine-3,5-dicarbonitrile synthesized by three stages from dimethylaniline. The study of the spectral-luminescent properties showed the presence of fluorescence in solutions with a maximum in the region of 432–473 nm and a quantum yield of up to 29.5%, and in the solid state with a maximum in the region of 446–472 nm.
