Synthesis and properties of the 5,10,15-trimesityltruxen-5-yl radical

Article abstract of DOI:10.1021/ol402153w

The synthesis of a long-lived, truxene-based radical that is highly delocalized and exhibits a narrow EPR absorption is reported. The radical is stable for multiple hours in a solution exposed to air and remains for months in the solid state under inert gas. Characterization and properties are discussed.
