High‐spin alignment in π‐conjugated Polyradicals: A Magnetic polymer

Extended dendritic, ladder, and cross‐linked polyradical frameworks empolying π‐conjugated backbones (e.g. see Fig.) show promise in the development of ferromagnetic polymers. Recent progress in this field is reviewed and the various classes of materials, for example polyacetylene‐, or polyphenylenevinylene‐based radicals, compared magnified image .
