Controlling the Guanidinium Cation Rotation by Cation–π Interactions

open access: yesAngewandte Chemie International Edition, EarlyView.
A lanthanide π‐container has been employed to trap a guanidinium cation inside the aromatic cavity by cation–π interactions. X‐ray crystallography and solid‐state nuclear magnetic resonance (NMR) spectroscopy at fast magic‐angle spinning (MAS) frequencies have been utilized to probe the underlying host–guest interactions.
