Visualizing the Entire Range of Noncovalent Interactions in Nanocrystalline Hybrid Materials Using 3D Electron Diffraction

Abstract: Noncovalent interactions are essential in the formation and properties of a diverse range of hybrid materials. However, reliably identifying the noncovalent interactions in nanocrystalline materials remains challenging using conventional methods such as X-ray diffraction and spectroscopy. Here, we demonstrate that accurate atomic positions including hydrogen atoms can be determined using three-dimensional electron diffraction (3D ED), from which the entire range of noncovalent interactions in a nanocrystalline… Show more

“…[16e, 18] Compared to organic cocrystals, our understanding of NCIs in hybrid, organic-inorganic supramolecular materials is less developed. [19] Metal organic frameworks (MOFs) are the most common type of hybrid material built on covalent interactions between the metal cation and organic linkers. As a result, NCIs do not dictate their primary architecture, but instead, have an impact on the assembly of higher order secondary, tertiary, and quaternary architecture.…”

“…16,17 Non-covalent interactions encompass hydrogen bonding, van der Waals forces, coordination bonds, attractive and repulsive interactions, etc. [18][19][20] In theory, repulsive and attractive interactions coexist in the system and can confine the motion of molecules. 21 Although often overlooked, repulsion plays a crucial role in stabilizing excitons and enhancing luminescence.…”

“…Non-covalent interactions are essential in the description of various interactions existing within supramolecules, layered materials, and biological systems including drug–solvent systems. The hydrogen bonding is stronger than the other non-covalent interactions and thus has greater significance. The IUPAC states that the hydrogen bond is an electrostatic interaction arising out of dipole–dipole interaction .…”
