Synthesis Of Photosensitizing Polymer Of Complex Between 4-(2' Pyrimidinylazo)-3-Hydroxy Dimethylaniline And Rhenium(I).

Abstract: 2-amino pyrimidine was diazotized with sodium nitrite and 3(M) hydrochloric acid and then it was coupled with 3-(dimethylamino) phenol at 00c. Rhenium complex was prepared by treating the azo dye with rhenium pentacarbonyl bromide in the solvent medium of dry toluene, stirred gently and refluxed for 8h under constant flow of nitrogen. Vinyl monomer was synthesized by treating the rhenium complex with methacryloyl chloride at room temperature for 50h. Polymer was synthesized by treating the vinyl monomer with styrene in the solvent medium of DMF at 1100c for 80h in presence of nitrogen .
