Abstract

The near-infrared fluorescent probes S1 and S2 based on the BODIPY skeleton were designed and synthesized. They showed different selectivity in various aqueous buffer solutions. Judicious choice of buffer solutions can modulate the selectivity of fluorescent sensors toward a specific metal ion.
