its novel chelates of some 3d series of transition metal ions had been prepared and characterized. The structural properties of the titled compounds were explored using elemental analyses, spectroscopic techniques (UV–visible, MS, and FT-IR), molar conductivity, and magnetic susceptibility measurements. The scanning electron microscope (SEM) showed that the ligand and its metal chelates exist in stick
4,6-Disubstituted-3-cyano-2-methylpyridines, easily prepared by treating alpha,beta-unsaturated carbonyl compounds with beta-aminocrotononitrile in the presence of potassium tert-butoxide, have been found to show intense fluorescence in the region of 400-552 nm. 3-Cyano-4,6-bis(4-methoxyphenyl)-and 3-cyano-4,6-di(2-furyl)-2-methylpyridines show more intense fluorescence than 7-diethylamino-4-methylcoumarin. The 3-cyano group of pyridines increases the fluorescence intensities and improves photostabilities.
