Supercapacitor : A π conjugated microporous polymer with an aza‐fused framework is reported. The porous framework is conductive and allows electrolyte ions to move into the pores because of structural features (see picture). The material becomes highly co‐operative in the formation of electrostatic charge‐separation layers, shows exceptional capacitance in supercapacitive energy storage, provides high energy densities, and offers an excellent cycle life.
