UV-vis spectral (a) and fluorescence (b) changes of compound 5 (4 × 10–5 mol.L−1) upon the addition of H2PO4−. All spectra were recorded in DMSO solution, (a) H2PO4−: ((0–8) × 10−5 mol·L−1); (b) H2PO4−: (0–20.8) × 10−5 mol·L−1), λex = 412 nm. Arrows indicated the direction of increasing anion concentration.
