The dimer imprints its shape and symmetry to the captured xenon atom, as demonstrated by Xe-129 NMR spectroscopy, single-crystal X-ray diffraction, and computational studies. The dimers self-assemble hierarchically into tubular structures to form a porous supramolecular architecture, whose cavities are filled by small molecules and gases.engXenonHost-guestCyclic peptideSelf-assemblyGas confinement2306 Química orgánicaTight Xenon Confinement in a Crystalline Sandwich-like Hydrogen-Bonded Dimeric Capsule of a Cyclic Peptidejournal article10.1002/anie.201906599open access
