Abstract
4-nitro benzene diazoniumsulphatewas prepared by the diazotization reaction of 4-nitro aniline with sodium nitrite and concentrated sulphuric acid at 00 c.Thenthe diazonium salt was coupled with 3-amino-9-ethyl carbazole dissolved in acetic acid at 00 c.The obtained azodye namely 4-azo-(4’ - nitro-1’-phenyl) 3-amino-9-ethyl carbazole was purified and characterized by IR,UV and NMR spectroscopy. 2-methacryloyl-3-(4-azo-4’-nitro1’-phenyl) amino-9-ethyl carbazole was synthesized by the reaction of 4-azo-(4’-nitro-1’-phenyl)-3- amino-9- ethyl carbazole with methacryloyl chloride in the solvent medium of THF under stirring for 50h.Lastly,the polymer was synthesized by the radical polymerization of 2-metharyloyl-3(4-azo-4’-nitro-1’-phenyl)-3-amino-9- ethyl carbazole with methylmethacrylate by using AIBN as radical initiator under stirring at 1100 c in the solvent medium of DMF for 80h. All the monomers and polymer was characterized by IR,UV and NMR spectroscopy.
