One route for non-destructive functionalization of graphene is ππ interfacing

state of the carbon atoms on graphene such that the high mobility of graphene is retained.
Here, the π electrons on graphene enable ππ interfacing with π–activated polyaromatic
molecules like anthracene, pyrelene, pyrene, coronene, etc. Polycyclic aromatic compounds
can bond with one another via π–orbital overlapping to form π π bond, which is stronger
than hydrogen bond, van der Waals, and dipole–dipole interactions (
