Novel Synthesis and Characterization of N‐Heterocyclic Azo Dyes with Acrylic Polymer for Thin Film Coatings

Abstract

Nitrogen-containing heterocyclic compounds are an important class of compounds in dyeing and textile industries.New nitrogen containing heterocyclic azo compounds have been synthesized by using gold nanoparticles (AuNPs) as a catalyst having a particle size of 15 nm. AuNPs play an important role in the coupling reaction to produce new heterocyclic azo pigments. These azo pigments were tested to solubility, light fastness, and durability. These synthesized nitrogen-containing heterocyclic pigments were characterized by melting points, UV-vis, FT-IR, and 1 H NMR spectroscopy for their characteristics and structural features. After analysis, these pigments at lower concentrations were blended with the n-butyl acrylate-co-methyl methacrylate (n-BA-co-MMA) polymer. These blended pigments were coated on a simple silica glass surface by following the simple deep and dry method. The coupled azo pigment shows excellent binding strength with poly(n-BA-co-MMA) acrylic polymers. C

“…9 It has been extensively investigated how the metal complexes of hydrazones, which include heterocyclic moieties comprising nitrogen, oxygen, and sulfur as hetero-atoms, interact with biological activity. 10 Furthermore, a wide range of β-diketone members have been utilized for a long time in enzymesupramolecular chemistry coordination chemistry as parts of multidentate ligands. As a result, β-diketone coordination's extensive structure has lately been studied.…”
