Abstract
A series of 3-cyano-4-pyrenyl-6-substituted-2-pyridone derivatives was prepared by the cyclization of ethyl 2-cyano-3-pyrenyl acrylate with aryl methyl ketones in the presence of ammonium acetate. The structures of the compounds were confirmed by spectral and element analysis. The fluorescence and colour parameters of the 3-cyano-4-pyrenyl-6-substituted-2-pyridones were also investigated.
