Physisorption of bromopentafluorobenzene (C 6 F 5 Br) on graphene can occur due to the unique σ-hole and π-hole characters of C 6 F 5 Br and the rich π-electrons region of graphene, leading to the formation of three types of π-hole···π and σ-hole···π interactions. The π-hole···π interactions are even stronger than the σ-hole···π interactions. The property of graphene was significantly affected by such physisorption.

石墨烯通过 π-hole...π 和 σ-hole...π 相互作用的非共价功能化

由于 C 6 F 5 Br 独特的 σ 孔和 π 孔特性以及石墨烯的丰富 π 电子区域，可以发生溴五氟苯 (C 6 F 5 Br) 在石墨烯上的物理吸附，导致形成三种类型的π-hole...π 和 σ-hole...π 相互作用。π-hole...π 相互作用甚至比σ-hole...π 相互作用更强。这种物理吸附显着影响了石墨烯的性质。
