Two distyryl-BODIPY-based NIR red-shifting ratiometric fluorescent probes are reported: KBHR-1 for pH and KBAHgR-1 for Ag+ and Hg2+. KBHR-1 showed a red-shifting ratiometric response to pH in the NIR region. The identical fluorophore core structure applied to KBAHgR-1 with a different recognition moiety resulted in a ratiometric response to Ag+ and Hg2+ in the NIR region.
