Incorporating cation-π interactions into classical fixed-charge force fields has historically posed challenges. To address this, we adopted the methodologies of Li et al. for incorporating ion-induced dipole interactions into the LJ potential to model cation-π interactions, which we refer to as the LJ-ID potential. Using this approach, we optimized the free parameters of the induced dipole interactions through a unique bottom-up strategy. This process began with the calculation of the reference binding energy landscape using DFT theory. We then optimized the free parameters of the LJ-ID potential by comparing the MS simulation binding energies with DFT results.
