m-Phenylene-linked aromatic poly(aminium cationic radical)s: persistent high-spin organic polyradicals.
[structure: see text] High molecular weight and networked aromatic polyamines prepared by palladium-catalyzed polycondensation were oxidized to yield the corresponding poly(aminium cationic radical)s, which displayed a substantial stability and an intramolecular ferromagnetic interaction of eight or nine spins.
