Abstract

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.

6-烷基氨基-2-氨基-4-[(4-（二甲氨基）苯基]吡啶-3,5-二碳腈的合成及光学性质

以N，N-二甲基苯胺为起始原料，经三步合成2-氨基-6-氯-4-[4-（二甲氨基）苯基]吡啶-3,5-二腈，与伯胺和仲胺反应得到6-烷基-氨基-2-氨基-4-[4-（二甲氨基）苯基]吡啶-3,5-二腈。后者在溶液中表现出荧光，最大发射波长为λ 432 ~ 473 nm，量子产率高达29.5%；在固体中表现出荧光，最大发射波长为λ 446 ~ 472 nm。
