Selective Saccharide Recognition Using Modular Diboronic Acid Fluorescent Sensors

Abstract

Abstract Modular diboronic acid receptors R ‐ 1 and S ‐ 1 were synthesized and found to be selective fluorescent chemosensors for saccharides. The fluorescence intensity of R ‐ 1 and S ‐ 1 increased on addition of saccharides due to the formation of intramolecular 1:1 cyclic complexes. In general, R ‐ 1 has higher binding constants and produces a higher fluorescent response with saccharides than S ‐ 1 .
