摘要：

A series of hetarylazo dyes was synthesized by coupling reaction of 4-aryl-2-aminothiophenes derivatives with diazotized 4-nitro-aniline, 5-nitro-2-aminothiazole and 6-nitro-2-aminobenzothiazole, respectively, as diazo components. Characterization of these dyes was carried out by spectral and elemental analyze. The solvent effects of dyes in the visible absorption spectra were also evaluated. (C) 2003 Elsevier Ltd.
