Cover Story: The complexation abilities of cucurbiturils (CBs) could be enhanced with the assistance of metal cations, which can exert a dual effect on the complexation process: either by competitively binding to the host entity or cooperatively associating to the CB[n]-guest structures. The current study focuses on the role of two metal species (Mg2+ and Ga3+) in the complex formation of CBs with three dye molecules: Thiazole Orange, Neutral Red, and Thioflavin T. Various key factors influencing the process have been recognized such as the pH and dielectric constant of the medium, cavity size of the host, Mn+ charge, and presence/absence of hydration shell around the metal cation. The results obtained from density functional theory (DFT) calculations shed new light on several aspects of the cucurbituril complexation chemistry. View this paper
