Synthesis and characterization of 2-(4-aryl-3-cyano-6-methylpyridin-2(1H)-ylidene)malononitriles

The synthesis of pyridine derivatives containing a buta-1,3-diene-1,1,3-tricarbonitrile fragment via the base-promoted reaction of benzalacetones and malononitrile dimer with subsequent oxidation is described. The influence of the substituents on the spectral-luminescent and electrochemical properties was also investigated.
