SENSING DEVICES AND CHEMOSENSORS AND COMPOSITIONS RELATING THERETO

摘要

A composition includes a fluorophore, a spacer bound to the fluorophore and a receptor having an unsaturated heterocycle ring bound to the spacer. The spacer is methylamine. The receptor and/or the spacer has a receptor sidechain bound to the unsaturated heterocycle ring and/or a spacer sidechain bound to the methylamine, respectively. The composition may be employed as a chemosensor configured to capture an ion in a fluid medium. The chemosensor may further be incorporated into a sensing device configured to detect the ion and calculate a concentration of the ion in the fluid medium.
