摘要
A series of some new bis-hetaryl monoazo dyes derived from different heterocycles has been synthesized from the coupling reactions of diazotized diazo components, polysubstituted 2-aminothiophenes with the corresponding coupling components, 2-pyridone and 5-pyrazolone derivatives, respectively. The structures of these bis-hetaryl azo dyes were confirmed by FT-IR, H-1-NMR and mass spectroscopy and elemental analyses. Their solvatochromic properties in different solvents were also investigated. (C) 2003 Elsevier Ltd. All rights reserved.
