Treatment of polyarylmethyl diethers with lithium metal in THF gave the corresponding carbodianions; subsequent oxidation with iodine at 180 K produced diradicals, which were studied in frozen THF solutions by SQUID magnetometry in the 2–100 K temperature and 0–5.5 T magnetic field ranges. Magnetization dependence on both the temperature and magnetic field was compared to the model based upon the Heisenberg Hamiltonian plus mean field. Small intramolecular magnetic interactions were found; both diradicals are triplet ground states.
