The use of rhodanine derivative compounds as sensormaterials in different analytical techniques

Rhodanine, also known as 2- thioxo-4-thiazolidinone, is a five-membered cyclic compound containing sulfur, oxygen and nitrogen, and its compounds have found significant applications in photochemistry, medicinal chemistry, biochemistry, and various other industries. The –NH group in rhodanine compounds allows for hydrophobic interactions, hydrogen bonding, and complexation with metal ions. Analytical chemists have exploited these properties in order to use rhodanine derivatives as sensor materials, and developed sensors suitable for use in many areas. Rhodanine derivatives exhibit properties significantly superior to many organic compounds known as sensor materials, making them highly suitable as sensor materials. This review provides an overview of the uses and applications of rhodanine derivative molecules as sensor materials in various analytical techniques, including colorimetric, fluorescence, or electrochemical methods.
