N2 - The planar, magnetic isomer is the most stable form of interior graphene monovacancies, whereas the nonplanar, nonmagnetic spiro isomer is more stable for those closer to the edge of graphene sheets. On thermal annealing, interior monovacancies migrate towards the outermost periphery of graphene flakes. The spiro isomer is a suitable structural building block for the synthesis of carbon spiral helices (see picture). (Figure Presented)
