The synthesis of novel highly efficient fluorescent dyes of 4-amino-2-chloro-6-arylpyridine-3,5-dicarbonitrile series via heterocyclization of aryl(heteryl)methylidene derivatives of malononitrile dimer bearing electron-donor groups was described. Solvatochromic behavior and substituents effect on the spectral-luminescent properties were also investigated. Strong solvatochromism and high relative fluorescence quantum yields up to 0.92 despite the large Stokes shift values and were observed.
