A novel phenanthridinone based conjugated monomers were directly polymerized by electrochemical polymerization on the ITO glass substrate. The resultant polymer contained removable side chains to generate the porous structure upon thermal annealing. The annealed polymer film was further doped to enhance the electrical conductivity. The area capacitance of the polymer thin film electrode reached 95 mF/cm2. This polymer film was used as the anode in the asymmetric supercapacitor and the vertically aligned carbon nanotubes were used as the cathode. The asymmetric supercapacitor device exhibited area based energy density over 300 μWh/cm2 and the capacitance retention reached 85% after 10000 cycles.
