H. Tukada, DIRADICAL DIIONS OF M-BIS(NAPHTHYL) AND (ANTHRYL) PHENYLENES AS NEW HIGH-SPIN MOLECULES, Journal of the Chemical Society, Chemical Communications, (19), 1994, pp. 2293-2294
Ferromagnetic spin alignment is observed in double one-electron-oxidiz
ed or -reduced conjugated molecules, m-bis(9-anthryl) phenylene dicati
on diradical 1(2.+) and m-bis(1-naphthyl) phenylene dianion diradical
2(2.-), based on EPR experiments at cryogenic temperature.
