A novel electron-deficient macrocycle, pillarquinone (P[Q]6), has been synthesized for the first time by both chemical and electrochemical oxidation of pillararene, showing clear hexagonal columnar stacking in the solid state. Cathodic voltammetric studies of P[Q]6 revealed that three electrons are injected first, followed by stepwise one-electron reductions. Read More
