Original Article


Ditopic receptors based on cyclodextrins bearing a metal binding site were used as enantioselective fluorescence sensors, which were able to generate different responses in the presence of d- or l-amino acids. The performances of the selectors as a function of their structure were evaluated, and the same analysis was extended to other analytes. In this work, this approach is used for the enantiomers of a series of amino acid derivatives and in particular of 2-aminocaprolactam. The results showed that the ability of these sensors to perform enantiomeric analysis can be extended to other analytes of interest in organic synthesis such as amino acid amides and α-aminolactams.
