Magnetic properties of ferrocene‐based conjugated polymers

Abstract

A novel route to organic ferromagnetic materials is proposed that is based on the stability of spin‐containing organometallic moieties such as ferricenium and the electronic or topological interactions contributed by a polymer. The magnetic properties of the new high‐spin polymers (see Figure) are shown to be sensitively dependent on the chemical nature of the bridge linking the ferricenium units.

New ferrocene‐containing copolyesters

“…Ferrocene units incorporated into polymers seem to be useful for several applications, e. g. for catalyzing redox reactions, as organic ferromagnetic materials 15) or as organic semiconductors la). Polymer-attached ferrocene compounds are used for medical applications, e. g. in cancer treatment 17).…”

Direct observation of electronic and nuclear ground state splitting in external magnetic field by inelastic neutron scattering on oxidized ferrocene and ferrocene containing polymers

“…While ferrocene itself is diamagnetic, paramagnetic and even ferromagnetic susceptibilities have been reported for ferrocene containing polymers [10,11]. In the case presented here, the oxidation a e-mail: appel@ill.eu with iodine causes one unpaired electron leading to a magnetic moment on the ferrocene complex.…”

“…This ''in chain'' approach is preferred to the pending-group one for applications exploiting the electronic delocalization of the tricyclic units, such as OPVs and molecular electronics. the first approach, the conjugated chain is interrupted by the metal [214][215][216] and is not considered here as representative of hybrid compounds. The first hybridization was pioneered by Yamamoto from polypyridine [217] complexed by ruthenium.…”
