A Ditopic Fluorescence Sensor for Saccharides and Mercury Based on a Boronic‐Acid Receptor and Desulfurisation Reaction

Abstract: Two boron-contained fluorescent sensors, 1 and 2, based on coumarin have been prepared. The fluorescence response of the two systems was investigated with addition of saccharide and mercury ions. Sensor 2 behaves as a bifunctional fluorescent switch with chemical inputs of D-fructose and mercury ions.

“…Recently, efficient bifunctional fluorescent probes garnered substantial interest because they can be used for the simultaneous detection of two different analytes. For example, certain bifunctional fluorescent probes were capable of sensing Hg( ii ) along with another analyte such as Ag( i ), Cu( ii ), Fe( iii ), Al( iii ), pH change, saccharides or F – . A novel chlorinated coumarin‐malononitrile fluorescent probe with three potential reaction sites was developed, and it demonstrated a highly selective and rapid response to hydrogen sulphide and GSH .…”

“…As described in a previous study, 31 4-diethylaminosalicylaldehyde (1.93 g, 0.01 mol), diethylmalonate (1.92 g, 0.01 mol), glacial acetic acid (0.1 mL) and piperidine (0.1 mL) were dissolved in absolute ethanol (40 mL) and refluxed for 4 h. The mixture was cooled to room temperature and filtered, and the solvent was removed under reduced pressure. A yellow crystalline solid 4 was obtained by recrystallization from ethanol with a 69% yield and a melting point of 85.9 °C.…”

“…However, the design and synthesis of such a multi-targeted sensor are challenging due to the complex architectures ( i.e. , compatibility of the functional motifs), multi-step reactions, and cumbersome purifications. Consequently, synthesis and properties of multi-targeted sensors are scarcely reported and efforts have to be dedicated for the facile synthesis procedure.…”
