Synthesis and spectral properties of hetaryl monoazo dyes derived from 2-amino-5-nitrothiazole
Various hetarylazo dyes have been synthesized by coupling reactions between diazotised 2-amino-5-nitrothiazole and 2-chloroaniline, 1,3-dihydroxybenzene and N-phenyl naphthylamine. Spectral measurements were carried out in different solvents. The solvatoc

Studies on nonlinear optical polyurethanes containing heterocyclic chromophores
This paper presents the synthesis of highly stable nitro-substituted thiazole, benzothiazole and thiadiazole chromophores. With these, a series of second-order nonlinear optical (NLO) responsive polyurethanes were successfully synthesized from tolylene-2,
