A BODIPY based probe for the reversible “turn on” detection of Au(III) ions

A new “turn on” fluorescent probe for the rapid and selective detection of Au3+ ions over other metal ions was developed. The probe design was constructed on a BODIPY-2-aminopyridine skeleton showing a weak fluorescence emission signal which increased substantially after the coordination of $Au^{3+}$ ions. The probe displayed remarkable sensing performances such as a low limit of detection (17 nM), a short response time (
