Fig. shows the geometries and molecular orbitals of nanographene models having a pentagon and heptagon as a structural defect. Both the HOMOs and LUMOs of the structural models were relatively localized around the edges of the curved nanographene structures, and the excellent chemical and electrochemical stability of the NPGs can be explained by the lower presence of reactive edges, as confirmed by TPD analysis. 3.
