Synthesis of Cobalt-Complex Azo Dye from 2, 2[Benzene-1, 3-diyl di-(E)-diazene-2, 1-diyl] bis (4-nitroaniline)
Résumé
The aim of this investigation is to carry out the synthesis of bisazo dye 2,2[benzene-1,3-diyl di(E)diazene 2,1-diyl]bis(4-nitroaniline). The synthesis was conducted through the diazotization and coupling of m-phenylene diamine with 4-nitroanline leading to the prodn. of azo metal (II) complex of Cobalt. Characterization of the ligand and the metal complex was carried out using various 34hysic-chem. techniques. The metal chelates have a metal to ligand ratio of 1:1. The synthesized azo metal (II) complex dye had a potential application for high d. optical recording media due to their good absorption spectra and high thermal stability.
