Abstract

A purely organic, high-spin, and durable polyradical molecule was synthesized: It is based on the non-Kekulé-and non-disjoint design of a π-conjugated poly (1, 2-phenylenevinylene) backbone pendantly 4-substituted with multiple robust arylaminium radicals. 4-N, N-Bis (4- methoxy-and-tert-butylphenyl) amino-2-bromostyrene 5 were synthesized and polymerized with a palladium-phosphine catalyst to afford the head-to-tail-linked polyradical precursors ...
