Synthesis and solid-state fluorescence of 2-alkylamino-4-aminopyridine-3,5-dicarbonitriles
摘要:
Reactions of 4-amino-2-aryl-6-chloropyridine-3,5-dicarbonitriles with primary and secondary amines afforded 2-alkylamino-4-amino-6-arylpyridine-3,5-dicarbonitriles which showed solid-sate fluorescence in the violet or blue region with the emission maxima in the lambda range 400-460 nm.
