Abstract
The polycondensation of 2-hydroxy-4-ethoxybenzophenone with 1, 3 butane diol was carried out in presence of polyphosphoric acid as a catalyst at 155 °C for 10 h to synthesize desired resin. The resin was used to synthesize polymer-metal complexes with 4f-block elements. The resin and its polymer-metal complexes were characterized on the basis of elemental analyses, electronic spectra, magnetic susceptibilities, FTIR, NMR and Thermogravimetric analyses. Morphology of resin and its polymer-metal complexes was studied by SEM. Catalytic activity of selected polymer-metal complexes in organic synthesis was examined. Antimicrobial activity of polymer-metal complexes against Escherichia coli, Bacillus subtilis, Staphylococcus aureus (bacteria) and Saccharomyces cerevisiae (yeast) were measured. It is observed that polymer-metal complexes are efficient and effective catalysts and antimicrobial agents.
