Abstract

Solution NMR provides valuable structural information on supramolecular complexes, the dynamics of their formation, and possible rearrangement between isomeric forms or the interplay between hosts and guests in supramolecular cavities. The atomic resolution of NMR provides direct access to the symmetry properties of supramolecular species. Line shapes in NMR spectra are sensitive to the time scale of dynamic processes. NOESY and ROESY experiments are among the most powerful tools to characterize supramolecular structures, although the dynamics of supramolecular complexes is inextricably mixed in these experiments.

Transient supramolecular interactions between low-molecular-weight-guests and macromolecular hosts detected by solution NMR enable the use of low-molecular-weight spies to report on large, NMR invisible, structures. This concept extends the interfaces between supramolecular chemistry, biomolecular structure, and material sciences.
