Synthesis and Characterization of Azobenzene Derived from 8-aminoquinoline in Aqueous Media

Abstract

A series of novel 8-(aryldiazenyl)quinolones have been synthesized effectively with excellent yields by using 8-amimoquinoline and a variety of aryldiazonium salts containing electron donating and withdrawing moieties in aqueous media. The structure of the synthesized azo dyes has been characterized by NMR, FTIR, mass spectroscopy, and UV–Vis techniques. The compounds’ absorption maxima values are in the range of 427 nm and 445 nm due to ?-?* charge transfer transition. It can be evaluated that azobenzenes have more absorbance ability in the strong donor systems. © 2022 Elsevier B.V., All rights reserved.
