Abstract One water stable three-dimensional coordination polymer {[Zn(TTPA)]·1.5DMA}n (Zn-1) was successfully synthesized via solvo-thermal reaction of a bifunctional ligand 2,5-bis-(1,2,4-triazol-1-yl)-terephthalic acid (H2TTPA) and Zn(NO3)2. Single-crystal X-ray diffraction analyses proclaimed that Zn-1 is a 3D framework with one-dimensional channels long c direction. Further topological studies revealed that polymer Zn-1 characterized as a (4,4)-connected binodal net with Schlafli symbol as {42.84}. In addition, the luminescent researches indicate that complex Zn-1 exhibits not only excellent recognition abilities of Fe3+, Cr2O72− and antibiotics (NFT, NFZ and DTZ) via luminescence quenching mechanism, but also efficient “turn-on” fluorescence sensing property of pyridine. Zn-1 is the first MOF material with multi-sensing performances of Fe3+, Cr2O72−, antibiotics and pyridine in aqueous media.
