A) Ultraviolet titration experiment of TP‐MIVC (10 × 10−6 m) in pH 7.4 PBS buffer solution with the addition of H2S (0–200 equiv.). B) Fluorescence titration experiment of TP‐MIVC (10 × 10−6 m) in buffer solution with increasing of H2S (0–200 equiv.) at room temperature. Inset: Trend of fluorescence changes at 550 nm of TP‐MIVC (10 × 10−6 m) with increasing of H2S. C) Absorption spectra of TP‐MIVC (10 × 10−6 m) in the presence of various relevant analytes at room temperature. D) Fluorescence responses of TP‐MIVC (10 × 10−6 m) in the presence of various relevant analytes.
