Graphene is considered one of the most promising materials for futureelectronic. However, in its pristine form graphene is a gapless material, whichimposes limitations to its use in some electronic applications. In order tosolve this problem many approaches have been tried, such as, physical andchemical functionalizations. These processes compromise some of the desirablegraphene properties. In this work, based on ab initio quantum moleculardynamics, we showed that a two-dimensional carbon allotrope, named biphenylenecarbon (BPC) can be obtained from selective dehydrogenation of porous graphene.BPC presents a nonzero bandgap and well-delocalized frontier orbitals.Synthetic routes to BPC are also addressed.
