Phenoxyl radicals ferromagnetically attached to a cyclic pi-conjugation: 2,8,14-Trisoxyphenyltribenzotrisdehydro[12]annulene
A dehydro[12]annulene C-3-symmetrically annelated with a phenoxyl-bearing benzene was synthesized. The dehydroannulene molecule was a quartet in the ground state, and the cyclic and planar pi -conjugation of the dehydroannulene acted as an effective ferromagnetic coupler between the pendant spins.
