Physical Properties of Thiazyl Radicals Toward Conductive and Magnetic Materials

Abstract

Heterocyclic thiazyl radicals possess unique chemical and physical properties, as building blocks for molecule‐based conductors, superconductors, and magnetic materials. They do not need protecting groups on their molecular skeletons, so that the lack of such substituents permits close packing in the solid state. Moreover, thiazyl radical solids often involve a multidimensional network consisting of π–π overlaps and S⋯N contacts. In this article, we describe various physical properties of thiazyl radicals such as drastic phase transitions, ferromagnetic couplings, nonlinear transport, and high photoconductivities. They are highly expected to be utilized in developing organic electronics/spintronics.
