Synthesis and characterization of conjugated polymers containing first row transition metal complexes

Abstract

A series of novel conjugated polymers containing first row transition metal complexes have been synthesized and characterized. Metal complexes including Mn(II), Fe(II), Co(II), Ni(II), and Cu(II) were incorporated into the bipyridine coordination sites of the conjugated polymer backbone. Upon inclusion of the metal complexes the absorption bands of the polymers were red-shifted and metal-to-ligand charge transfer (MLCT) bands were observed. The magnetic properties of these polymers were studied and the results showed that they all had high paramagnetic susceptibility; where applicable they were all stable in the high-spin state. Their large free spins and stability makes them promising as magnetic materials.
