Synthesis and Optical Properties of Ethyl 2-Cyano-2-[3,4-dicyanopyridin-2(1H)-ylidene]acetate Derivatives

Derivatives of ethyl 2-cyano-2-[3,4-dicyanopyridin-2(1 H )-ylidene]acetate have been synthesized by reaction of 2-chloropyridine-3,4-dicarbonitriles with ethyl cyanoacetate. The synthesized compounds showed solid state fluorescence with the emission maxima located in the range λ 619–641 nm; the emis...

Zusammenfassung:	Derivatives of ethyl 2-cyano-2-[3,4-dicyanopyridin-2(1 H )-ylidene]acetate have been synthesized by reaction of 2-chloropyridine-3,4-dicarbonitriles with ethyl cyanoacetate. The synthesized compounds showed solid state fluorescence with the emission maxima located in the range λ 619–641 nm; the emission maxima in solution range from λ 392 to 486 nm, depending on the solvent.
