Hydrothermal reaction of the multidentate N-donor ligand 14(1H-1,2,4-triazol-1-yl)methyl)-3-(4-pyridy1)-5-(2-pyridy1)-1,2,4-triazole (2,4'-tmbpt), 5-hydroxy-1,3-benzenedicarboxylic acid (5-OH-H(2)bdc), and Cd(CH3COO)(2)center dot 2H(2)O in the presence of NaOH afforded a coordination polymer [Cd(2,4'-tmbpt)(2)(5OH-bdc)]center dot 5H(2)O (1), which exhibits a 1D -> 2D -> 3D supramolecular architecture. The photoluminescent spectra of the compound in different aqueous solutions in the pH range of 1-14 have been investigated. The results indicate that compound 1 can be used as an efficient pH fluorescent sensor and molecular logic gate. The pH sensing mechanism of the compound has been discussed and proved by the UV-Vis spectra.
