Abstract

SPECTROSCOPIC PROPERTIES OF NOVEL AZO SCHIFF BASE DYES

Maged H. Muzael*

ABSTRACT

Novel aldehyde (3) was synthesized through azo coupling between 6- amino-2-mercaptopyrimidin-4-ol and 4-(dimethylamion) benzaldehyde. The new aldehyde was condensed with four different amines to give four new dyes (5a-d). The new dyes were characterised using spectroscopic methods such as I.R, 1H and 13C NMR. The electronic spectra of dye 3 was studied in solvents of varying polarity and displayed a bathochromic shift in the more polar solvents. The UV-visible spectra of the dyes 5 a-d showed a red shift following extension of the chromophores in these new dyes.

Keywords: azo dye; schiff base; pyrimidine; electronic spectra study.
