Herein, the assembly between the multi-functional 2-amino-4-sulfonyl-benzoic acid (H₂asba) and Cd(II) in the presence of the hydrophobic ligand 4-bis[(2-methyl-1H-imidazole-1-yl)methyl]benzene (2-mmzm) results in a novel hydrolytically stable 1D Cd(II)-FCP, {[Cd(asba)(2-mmzm)(H₂O)₂]•3H₂O}_n (1). The water tetramer-based hydrogen-bonded ring R₂²(8) bridges the chains into a 2D supramolecular layer. The novel discrete water decamer further links the layers into a 3D supramolecular network. 1 shows extremely acidic and basic resistance in a wide pH range of 1.0-12.0. More importantly, 1 exhibits accurate sensing of pH of the artificial gastric juices. Interestingly, 1 demonstrates solvent-dependent multi-responsive fluorescence sensing behavior to metal ions. 1 can sense Fe³⁺/Cu²⁺/Tb³⁺ in water, Fe³⁺/Cu²⁺/Tb³⁺/Co²⁺ in MeOH and Fe³⁺/Cu²⁺/Tb³⁺/Co²⁺/Ba²⁺ in ethanol, respectively. The fluorescence sensing of 1 toward Fe³⁺/Tb³⁺/Ba²⁺ is resulted from the structural collapse in the corresponding solvents. However, 1 keeps integrity and shows higher chemical resistance to Cu²⁺ and Co²⁺ in the corresponding solvents. The fluorescence sensing of Cu²⁺ can be ascribed to the photo-induced electron transfer (PET) and fluorescence resonance energy transfer (FRET) mechanism. The sensing of Co²⁺ can be attributed to the PET mechanism. The solvents have great influence on the sensing sensitivities to Cu²⁺ and Co²⁺. 1 shows the highest sensing sensitivity to Cu²⁺ and Co²⁺ in ethanol.
