The literature has shown numerous contributions on the synthesis and physicochemical properties of persistent organic radicals but there are a lesser number of reports about their use as building blocks for obtaining molecular magnetic materials exhibiting an additional and useful physical property or function. These materials show promise for applications in spintronics as well as bistable memory devices and sensing materials. This critical review provides an up-to-date survey to this new generation of multifunctional magnetic materials. For this, a detailed revision of the most common families of persistent organic radicals-nitroxide, triphenylmethyl, verdazyl, phenalenyl, and dithiadiazolyl-so far reported will be presented, classified into three different sections: materials with magnetic, conducting and optical properties. An additional section reporting switchable materials based on these radicals is presented (257 references).

“…From both the scientific and technological point of view, to afford examples of molecular devices as thermal or optical switching systems correlated with spins. [1][2] Several interesting example of organic photochromic and photomagnetic compounds such as azobenzene, diarylethene, spiropyran, terphenoquinone, anthracene, and naphthopyran have been reported, and their properties have been extensively investigated. [3][4][5][6][7] Aminoxyl radical moieties have been widely adopted in those compounds, because of their versatility and good stability in the field of material chemistry as building blocks for molecule-based magnetic materials.…”

Ten novel and stable free radicals of nitronyl-, imino-nitroxide and hydrazyl type compounds were synthesized and their physico-chemical properties investigated. UV-Vis and ESR spectroscopic data, as well as the lipophilicities and speci c hydrophobic areas of the compounds are compiled. The reaction of these radical compounds with nitric oxide and nitrogen dioxide was also investigated. The radicals synthesized, show selectivity in their reaction with these nitric oxides, depending on their structure (nitronyl-nitroxide radicals react with NO, while hydrazyl radicals react with NO 2 ). The processes are easily monitored by UVVis or ESR spectroscopy.

Organic Multifunctional Spin Systems Based on Aminoxyl Radicals

Abstract: Recent advances in the development of organic multifunctional spin systems are described. This includes systems with carrier transport properties, photo‐functionality, liquid crystallinity, and pressure functionality in which aminoxyl (nitroxide) radicals play a crucial roll.
