Abstract

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, 1H NMR and 13C 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.

► Five new benzoquinoline based heteocyclic monoazo dyes have been synthesized. ► Dyes showed yellow hues with remarkable light, wash and rubbing fastness properties. ► Quantum chemical studies showed that dye 6c and 6e are energetically more stable. ► Colorimetric data showed that dye 6b showed highest K/S value on polyester fiber.
