Magnetic properties of ferrocene‐based conjugated polymers

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. (Figure Presented.)
