Molecular Conductors from Neutral Heterocyclic Pi-Radicals

by Cordes, A. W.; Haddon, R. C.; Oakley, R. T.

Stable radical species (e.g. see Fig.) can form an alternative source of organic conducting materials. Suppressing the Peierls distortion and stabilizing the metallic state can be achieved by applying pressure or by developing materials with enhanced two- and three-dimensional interactions. Recent progress in the synthesis, and stabilization, for example through doping, is discussed.
