Abstract

Triphenylene core has a planar π-conjugated structure which is expected to allow radical generation at low oxidation potential and strong ferromagnetic interaction of the radicals' unpaired electrons. We reported the triradical, 2,6,10-tris(dianisylaminium)-3,7,11-tris(hexyloxy)triphenylene, with a quartet state (S = 3/2) at room temperature[1]. Connection of the module by satisfying non-Kekule and non-disjoint coupling fashion is supposed to yield a stable, high-spin purely organic polyradical. In this report, we designed and have synthesized poly(aminium triphenylene) 1 and poly(naphthylaminium triphenylene) 2 by extending the triradical. Spin alignment of 1 and 2 was discussed by SQUID measurement. It was expected that the quartet triaminium triphenylene module is effectively connected through the triphenylene and naphthalene structures.
