Enantioselective voltammetric sensor based on mesoporous graphitized carbon black Carbopack X and fulvene derivative.

For medicine and pharmaceuticals, the problem of determining and recognizing the enantiomers of biologically active compounds is an actual issue because the enantiomers of the same substance can have different effects on living organisms. This paper describes the development of an enantioselective voltammetric sensor (EVS) based on a glassy carbon electrode (GCE) modified with mesoporous graphitized carbon black Carbopack X (CpX) and a fulvene derivative (1S,4R)-2-cyclopenta-2,4-dien-1-ylidene-1-isopropyl-4-methylcyclohexane (CpIPMC) for recognition and determination of tryptophan (Trp) enantiomers. Synthesized CpIPMC was characterized by H and C nuclear magnetic resonance (NMR), chromatography-mass spectrometry, and polarimetry.
