Published: May 1, 2024

The stereospecific analysis of chiral molecules is an important issue in many scientific fields. In separation sciences, this achieved via the formation transient diastereomeric complexes between a selector and selectand enantiomers driven by molecular interactions including electrostatic, ion‐dipole, dipole‐dipole, van der Waals or π‐π as well hydrogen halogen bonds depending on nature selectand. Nuclear magnetic resonance spectroscopy modeling methods are currently most frequently applied techniques to understand selector‐selectand at level draw conclusions mechanism. present short review summarizes some recent achievements for understanding recognition selectors combining with and/or spectroscopic dating 2020 early 2024. include polysaccharide derivatives, cyclodextrins, macrocyclic glycopeptides, proteins, donor‐acceptor type selectors, ion‐exchangers, crown ethers, micelles. application ionic liquids deep eutectic solvents, further also briefly addressed.

Tailoring Chirality and Optimizing Enantioselective Recognition in Strategic Defect Engineering of Chiral Metal–Organic Frameworks

Analytical Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 20, 2025

Introducing chiral molecules into metal–organic frameworks (MOFs) to obtain MOFs (CMOFs), the tunability of their structures makes them a highly anticipated class materials for electrochemical sensing. However, structure CMOFs is often limited by synthesis challenges, and introducing leads decrease in internal space. This study introduces defect engineering strategy with defects, which an efficient method. The two constructed different not only have more recognition sites but also greatly increase substrate capacity due making wide range substrates enhancing enantioselective effect defective CMOFs. In addition, using MOF as carrier overcomes problem low conductivity molecules. Based on advantages CMOFs, we designed novel sensor excellent enantiomer performance. provides simple scalable synthetic method constructing defects high stability.
