|Molecular Dynamics of Cucurbituril Host-Guest Chemistry|
Molecular dynamics (MD) simulations have been used to study the dynamics of the inclusion complexes of Methyl viologen (MV) with cucurbit[n]uril, CBn, (where n = 6, 7 and 8) in aqueous solution. The obtained MD trajectories were analyzed and post processed using Molecular Mechanics-Poisson Boltzmann Surface Area (MM–PBSA) method to shed some light on the guest-host intermolecular forces that play a significant role in the formation of the CB inclusion complexes.
