Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Chiral recognition and separation methods have received a lot of attention due to the growing need for pure enantiomeric forms of substances. The separation of enantiomers is usually done with the aid of a chiral selector. Numerous chiral selectors, such as crown ethers, polysaccharides, antibiotics, etc., are extensively used in enantiomeric recognition studies; nevertheless, each one of them has limitations of its own. Recently, chiral ionic liquids (CILs), having inherent chirality due to the presence of a chiral cation or anion, have emerged as inexpensive and lucrative chiral selectors for enantiomeric recognition procedures. This article discusses the application of CILs in chiral recognition methods through spectroscopic techniques like UV-visible, NMR, and fluorescence spectroscopy. It also focuses on the mechanism behind chiral recognition.
