摘要：
Physisorption of bromopentafluorobenzene (C6F5Br) on graphene can occur due to the unique sigma-hole and pi-hole characters of C6F5Br and the rich pi-electrons region of graphene, leading to the formation of three types of pi-hole center dot center dot center dot pi and sigma-hole center dot center dot center dot pi interactions. The pi-hole center dot center dot center dot pi interactions are even stronger than the sigma-hole center dot center dot center dot pi interactions. The property of graphene was significantly affected by such physisorption.
