  6-dihydropyridine-3-carboxylates was developed consisting in the reaction of acetoacetic ester, aromatic aldehydes, and malononitrile dimer in the presence of sodium nitrite. Optical properties of synthesized compounds were investigated and it was demonstrated that they possessed intensive fluorescence in solution and in solid state with emission maxima in the yellow and green region of the visible light
