Electronic properties of 1,3,5-tris[4-morpholinophenyl]benzene: a new molecular switch

A new electron-donor, 1,3,5-tris[4-morpholinophenyl]benzene 1, was synthetised via nickel-catalysed arylamination reactions and characterised by cyclic voltammetry. It was found that electrochemical or chemical oxidation of 1 generates mono- or di(cation radical)s that are stable over 30 min at room temperature.
