摘要: Abstract A new class of ferromagnetic conjugated polymers is proposed. These have no built-in radicals, but spins are generated by doping. They an alternating -A-B-A-B- structure. a block which gives polaron on B couples the A-block spins. Possible ferromagnetism in this type demonstrated using PPP model.
