Homochiral metal-organic frameworks (MOFs) are exceptional media for heterogenous enantiodifferentation processes. Modifying available achiral structure-bearing MOF scaffolds is a preferred method to extend this class of materials. However, reported post-synthetic covalent chiralizations generally lead uniform, site-specific modifications. The use chemically versatile modifying agents, like aldehydes, may instead result in the statistical formation non-uniform anchored products. Such molecular non-uniformity and grain structure greatly increase system’s complexity. such therefore, necessitates broader, holistic characterization. present work explores adaptation imine chemistry chiralization. A chiral aldehyde ketone have been probed on two amine-functionalized substrates - MIL-125 NH2, UiO-66 NH2. NH2 modified with natural product-derived (R)-2,2-dimethyl-1,3-dioxolane-4-carboxaldehyde ((R)-1 aldehyde) was found best performance comprehensive toolbox characterization methods demonstrated robustly assess obtained material’s This includes high-resolution accurate mass electrospray ionization spectrometry (HRAM-ESI-MS) reveal competing reactions that yield set oligomer-rich structures. In silico modeling correctly predicted localization modification. modification mainly proceeded through formation, resulting surface enantioselector display formation. Restricted diffusion lengths solid phase infer good retention resolving power ascending van Deemter régimes chromatography. makes yielding material promising stationary candidate performant chromatographic enantioseparations.

Abstract Chiral inorganic nanomaterials (CINMs) have garnered significant interest due to their exceptional optical, electronic, and catalytic properties, offering promising advancements in energy conversion, data storage, catalysis, biomedicine. While traditional optical spectrophotometers reveal the chiroptical performance of CINMs on an ensemble level, direct structural visualization for qualitative quantitative discernment chiral features has become increasingly distinct with transmission electron microscopy (TEM) techniques. The need reasonable high‐standard discrimination requirements driven progress chirality‐based TEM technologies. Therefore, this review good season takes initiative summarize current technologies characterization, emphasizing a analysis atomic‐level features, 0D, 1D, 2D nanocrystals, assembled nanomaterials. Then, methods determining chirality is also highlighted, such as 3D tomography, further address evolution structures monitored by Ex‐situ In‐situ By providing roadmap challenges proposing future qualitative, quantitative, real‐time CINMs, it can drive innovations field well development
