A novel Triphenylamine‐BODIPY Schiff base fluorescent sensor (Probe 1) was designed and synthesized by “Click reaction”. It is a reaction‐based probe for Hg 2+ and Fe 3+ with high selectivity and sensitivity. The fluorescent quantum yield of Probe 1 at band 515 nm is 0.07. After treatment with Fe 3+ or Hg 2+ , the fluorescence intensity enhanced, and the fluorescent quantum yield is 0.64 for Probe 1/Fe 3+ and 0.58 for Probe 1/Hg 2+ respectively. The results of Job's plot experiment shows stoichiometry between Probe 1 and Fe 3+ or Hg 2+ is 1 : 2. The detection limit is 6.69× 10 −8 M for Fe 3+ and 2.24×10 −7 M for Hg 2+ . Water‐soluble fluorescent nanoparticles (FNPs) that encapsulate the probe are prepared, and the fluorescent quantum yield of FNPs is 0.16. Probe 1 has a great application prospect in biomedical, ion detection and is an excellent platform for developing multichannel reaction‐based probes.
