Abstract
Some non-Kekulé-type organic molecules exhibit a high-spin state on an intramolecular spin-exchange interaction. These high-spin molecules can be extended to the corresponding polyradicals with spins that are ferromagnetically aligned. Poly(4-oxyphenyl-1,2-phenyleneethynylene) was synthesized, and the effect of the head-to-tail connectivity on the ferromagnetic interaction is described.
