Synthesis and Optical Properties of 6-Alkylamino-2-amino-4-[(4-(dimethylamino)phenyl]pyridine-3,5-dicarbonitriles
2-Amino-6-chloro-4-[4-(dimethylamino)phenyl]pyridine-3,5-dicarbonitrile was synthesized in three steps starting from N,N-dimethylaniline, and its reactions with primary and secondary amines afforded 6-alkylamino-2-amino-4-[4-(dimethylamino)phenyl]pyridine-3,5-dicarbonitriles. The latter showed fluorescence in solution with an emission maximum in the range of λ 432–473 nm and a quantum yield of up to 29.5%, as well as solid-state fluorescence with a maximum in the range of λ 446–472 nm.
