Ferrocene-based poly(aroxycarbonyltriazole)s: synthesis by metal-free click polymerization and use as precursors to magnetic ceramics

Ferrocene-based poly(aroxycarbonyltriazole)s with high molecular weights and regioregularities were prepared in high yields by the efficient metal-free click polymerization of dipropiolates and the ferrocene-containing diazide under mild reaction conditions. The resulting polytriazoles are redox active, and could be used as precursors to generate soft magnetic ceramics with high magnetizability and low coercivity when pyrolyzed at elevated temperatures.
