Özet
Abstract: π--π Non-covalent interaction, especially important in intermolecular interactions involving (n)-Annulene-graphene aromatic rings in particular, is fundamental for exfoliate processes. The work detailed in this study involves the application of electronic structure for illuminating of the (π--π) interactions between (n)-Annulene solvents and graphene sheets. We have simulated the adsorption of several (n)-Annulene and its Aza-bora derivatives on a graphene sheet, using QM/MM method with ONIOM approach. The presences of these compounds significantly alter the overall magnitude of exfoliation due to (π--π) interactions between Annulene solvents and graphene through rising of the strong interactions including π-orbitals of the adsorbent. Adsorption of individual molecules and Aza-bora compound reflects a hierarchical balance of the especial interaction that determines the overall energy of adsorption. In addition, the nucleus independent chemical shifts (NICS) and statistical nucleus chemical shifts (S-NICS) values confirm the amounts of aromaticity and anti-aromaticity in those rings.
