| Abstract: | A new Zn(II) metal-organic framework was synthesized with 5-nitro-1,2,3-benzenetricarboxylic acid and auxiliary triazole ligand via hydrothermal method, namely, {Zn2.5(nbta)(trz)2(H2O)]·3H2O}n (1), where H3nbta = 5-nitro-1,2,3-benzenetricarboxylic acid and Htrz = 1H-1,2,4-triazole. 1 shows high thermal stability up to 150 °C under air atmosphere and water stability with the pH range from 1 to 12. Luminescent study shows that 1 displays a high-sensitivity sensing function for p-xylene in the three kinds of xylene isomers. |
