Graphical Abstract

How hosts handle a noble guest: A combination of NMR spectroscopy and quantum chemistry enabled thorough analysis of the noncovalent interactions inside a xenon–host complex. The validation of this approach with a family of cryptophane hosts derived by treatment of the structure shown with H2O2 paves the way for the design of potent smart hyperpolarized 129Xe NMR sensors.

Abstract

Gaining an understanding of the nature of host–guest interactions in supramolecular complexes involving heavy atoms is a difficult task. Described herein is a robust simulation method applied to complexes between xenon and members of a cryptophane family. The calculated chemical shift of xenon caged in a H2O2 probe, as modeled by quantum chemistry with complementary-orbital, topological, and energy-decomposition analyses, is in excellent agreement with that observed in hyperpolarized 129Xe NMR spectra. This approach can be extended to other van der Waals complexes involving heavy atoms.
