Polymeric, H-Bonded, and Chelatable Phenoxyl and Nitroxide Radicals

Abstract Various examples are described of a multi-strategy approach to improvement of multispin exchange design. For example, H-bonded benzimidazole 4-t-butylnitroxide shows apparent simple planar 2D-type interaction, with a Weiss constant of Θ = −4.24 K and an intraplane exchange interaction of J = −1.60 K.
