Abstract

The diazocoupling reaction of hexamethylenediamine, 5-amino-2-hydroxybenzoic acid, and ethylenediamine with benzoyl chloride and carbazole, respectively, in the presence of HCl, NaNO2, and 10% NaOH was used to create a series of azobenzene compounds. The reaction was stirred for an hour in an ice bath at 0–5°C.The resulting azobenzene compounds react with vinyl compounds, including trichloroethylene compounds. In the presence of nitrogen, 1-hydroxy cyclohexyl phenol ketone was used as the initiator in free-radical photopolymerization to polymerize azo benzene trichloroethylene Derivatives that included trichloroethylene molecules. FTIR, 1H, and 13CNMR have been used to characterise the spectroscopic properties of the small compounds and polymers of azobenzene.Azobenzene polymer thermal (DSC and TGA) methods were investigated.
