摘要

Some novel benzoquinoline based heterocyclic monoazo dyes have been derived by the diazotization of 1H-benzo[g]pyrazolo[3,4-b]quinoline-3-ylamine with various phenyl pyrazolone as coupling components. All the heterocyclic monoazo dyes have been characterized by elemental analyses and various spectral data (FT-IR, UV-Vis, p>1p>H NMR and p>13p>C NMR), and their 3D model structures were predicted through B3LYP/6-31G(d,p) method. The dyeing performance on polyester fibers inferred that all the dyes gave moderate to excellent fastness properties on fiber. In addition, colorimetric studies of synthesized dyes have also been discussed.
