Visualization of enantioselective recognition and separation of chiral acids by aggregation‐induced emission chiral diamine

Aggregate, 2023
Enantioselective recognition and separation are the most important issues in the fields of chemistry, pharmacy, agrochemical, and food science. Here, we developed two optically active diamines showing aggregation‐induced emission (AIE) that can ...

Comparison of the Performance of Different Bile Salts in Enantioselective Separation of Palonosetron Stereoisomers by Micellar Electrokinetic Chromatography

Molecules, 2022
Bile salts are a category of natural chiral surfactants which have ever been used as the surfactant and chiral selector for the separation of many chiral compounds by micellar electrokinetic chromatography (MEKC).

Silica Immobilised Chloro- and Amido-Derivatives of Eremomycine as Chiral Stationary Phases for the Enantioseparation of Amino Acids by Reversed-Phase Liquid Chromatography

Molecules, 2022
Macrocyclic glycopeptide antibiotics immobilized on silica are one of the effective classes of stationary phases for chiral recognition and HPLC separation of a wide range of optically active compounds.

Polysaccharide- and β-Cyclodextrin-Based Chiral Selectors for Enantiomer Resolution: Recent Developments and Applications

Molecules, 2021
Polysaccharides, oligosaccharides, and their derivatives, particularly of amylose, cellulose, chitosan, and β-cyclodextrin, are well-known chiral selectors (CSs) of chiral stationary phases (CSPs) in chromatography, because they can separate a wide range

Hydrodynamics of thermally-driven chiral propulsion and separation [PDF]

, 2023
Considerable effort has been directed towards the characterization of chiral mesoscale structures, as shown in chiral protein assemblies and carbon nanotubes. Here, we establish a thermally-driven hydrodynamic description for the actuation and separation

Chiral Separations of Pyrethroic Acids Using Cyclodextrin Selectors

Molecules, 2022
Pyrethroid insecticides are broadly used. They have low toxicity for warm-blooded living creatures, but high toxicity for both insects and fish. Therefore, it is important to reduce the environmental impact of pyrethroids.

Review on the enantioselective separation and environmental determination of chiral contaminates

浙江大学学报. 农业与生命科学版, 2002
Approaches to the chromatographic (GC, HPLC, CE, SFC and TLC) enantiomer separation and determination of chiral contaminates are reviewed. The enanriomers of chiral contaminates are selectively degradation and interaction in soil and water environment ...

An efficient approach to mechanically planar chiral rotaxanes

, 2014
We describe the first method for production of mechanically planar chiral rotaxanes in excellent enantiopurity without the use of chiral separation techniques and, for the first time, unambiguously assign the absolute stereochemistry of the products ...

Separation Of Methionine Enantiomers By Using Teicoplanin And Cyclofructan Columns

Nova Biotechnologica et Chimica, 2015
Methionine is a naturally occurring amino acid. Its enantiomeric separation by using high performance liquid chromatography on various types of chiral stationary phases was studied.
