High Field Solid-State NMR Spectroscopy Investigation of 15N‑Labeled Rosette Nanotubes: Hydrogen Bond Network and Channel-Bound Water

(15)N-labeled rosette nanotubes were synthesized and investigated using high-field solid-state NMR spectroscopy, X-ray diffraction, atomic force microscopy, and electron microscopy. The results established the H-bond network involved in the self-assembly of the nanostructure as well as bound water molecules in the nanotube's channel.
