A Glucose‐Selective Molecular Fluorescence Sensor

Abstract

Low concentrations of D-fructose and D-galactose do not hinder the detection of D-glucose with the fluorescence sensor 1. The diboronic acid 1 is easy to synthesize and forms a cleft structure in which monosaccharides bind with differing selectivity. The saccharide-diboronic acid 1:1 complexes are readily detected by their fluorescence.
