Synthesis, antimicrobial activity and application of some novel quinazolinone based monoazo reactive dyes on various fibres

The main target of this paper was to synthesize novel reactive dyes that not only give good dyeing property but also show pharmacological activity i.e. antimicrobial activity (antibacterial and antifungal). In this regard ten novel monoazo quinazolinone based reactive dyes (7a-j) were made by coupling of diazotised 3-{4-[4-amino-2-nitrobenzyl]-3-nitrophenyl}-7-chloro-2- phenylquinazolin-4(3H)-one (4) with various p-chloro anilino cyanurated coupling components (6a-j). The structures of all these synthesized dyes were confirmed by elemental analysis and spectral methods. The antimicrobial activity, colorimetric data, solvent effect and fastness properties of these dyes were also investigated.

Synthesis and photoreactions of aromatic diols containing bis (azo) and bis (o-nitrobenzyl) chromophores

Aromatic diols containing bis (azo) and bis (o-nitrobenzyl) chromophores viz., (4-hydroxyphenylazo)-2,2′-dinitrodiphenylmethane, 4-hydroxy-3-methylphenylazo-4′-hydroxyphenylazo-2,2′- dinitrodiphenyl methane and bis (4-hydroxy-3-methylphenylazo)-2-dinitrodiphenyl methane were synthesized from 4,4-diamino-2,2′-dinitrodiphenylmethane and phenol/O-cresol. As a result of photolysis, the azo group of the diols unergo trans-cis isomerisation and one of the o-nitrobenzyl groups of the diols undergo trans-cis isomerisation and one of the o-nitrobenzyl groups in them undergo redox reaction to nitronitrosocarbinol. There occurred a solubility difference between the irradiated and unirradiated diol. In solution, a photoswtiching behaviour was also observed.
