A thiourea‐based tripodal colorimetric anion sensor was synthesized. Its binding abilities with AcO ‐ and halide anions in DMSO were studied by UV‐Vis spectra. The sensor showed different color responses to these anions. The association constants and different stoichiometries were deduced by nonlinear least‐square curve fitting or linear fitting.
