Abstract

2-Substituted pyridinium hemicyanine dyes were synthesized in a fast, efficient and high yield by the condensation of 1,2-dimethyl pyridine salts with aromatic aldehydes in the present of piperidine under solvent-free microwave irradiation. The products were identified by ¹H NMR, MS, IR, UV-vis spectra and elemental analysis. Furthermore, spectrum property of N-methyl-2-(p-dimethylamino-styryl)pyridine hemicyanine dye was calculated.

Key words: 2-methyl pyridine, aromatic aldehyde, 2-substituted pyridinium hemicyanine dye, microwave irradiation
