为什么石墨烯不叫石墨苯？这结构不是更像苯吗？
命名者 Hanns-Peter Boehm 给出的答案： The suffix -ene is used for fused polycyclic aromatic hydrocarbons, even when the root of the name is of trivial origin, e.g. naphthalene, anthracene, coronene, etc. A single carbon layer of the graphitic structure can be considered as the final member of this series and the term graphene should therefore be used to designate the individual carbon layers in graphite intercalation compounds. 也有人这样解释 ，石墨层为大的共轭π键，标准命名为多烯，而苯可命名为环己三烯。
