Regarding the results with the smallest basis sets, such as 6-31G* (for which the CP-corrected and uncorrected values of ∆E int differ by as much as 30 kcal/mol), we note that the ratio |∆E int (no CP)/∆E int (CP)| ≈ 1.4. This is only slightly smaller than the ratio of ≈ 1.5 that is observed for the S66 dimers, using the same functional and basis set. For ωB97M-V/def2-SVP, this ratio is ≈ 1.3 for the graphene-oligothiophene systems. The similarity of these ratios suggests that neither the behavior of the functional, nor that of the CP correction, is fundamentally changed by moving to these larger systems. Instead, the larger convergence errors observed for the layered complexes reflects the size-extensivity of BSSE, which is often overlooked.
