Abstract
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 production of azo metal (II) complex of Cobalt. Characterization of the ligand and the metal complex was carried out using various 34hysic-chemical 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 density optical recording media due to their good absorption spectra and high thermal stability.
