Abstract

We describe two successful applications of our library based on host-guest inclusion complexes in cyclodextrins (CDs) and/or cucurbiturils (CBs) for the identification of organic compounds in aqueous media. Detection of amines, which have been found as a challenging compound class in previous works on chemical tongues, and quaternary ammonium salts (QAS), for which no sensor is available on the market, have been studied. Besides the clear need for new detection, identification and quantification techniques of such compounds in water, the main advantage of our approach is that an array made by combining simple basic dyes with commercial organic capsules allows a perfect discrimination for all the presented applications.
