A grossly warped nanographene and the consequences of multiple odd-membered-ring defects

A grossly warped nanographene, C80H30, that incorporates five 7-membered rings and one 5-membered ring embedded in a hexagonal lattice has been synthesized, isolated and fully characterized. Experiments revealing how the properties of such a large graphene subunit are affected by multiple odd-membered-ring defects are also reported.
