| Abstract: | The 5-methyl-1-(4-nitrophenyl)-1H-1, 2, 3-triazole-4-carboxylic acid (1) was synthesized by an improved method. By using the compound 1 as ligand, a new complex Cu(L)2]Cu(L)2(H2O)2] (2) was prepared firstly under hydrothermal condition. Both 1 and 2 were all used as exclusive fluorescence sensor for 2, 4, 6-trinitrophenol (TNP) for the first time. The fluorescence exploration demonstrated that they exhibit highly selective and sensitive (KSV = 393685 M?1 and KSV = 213269 M?1, respectively) sensing to TNP from other nitro aromatic compounds (NACs) with high quenching efficiency QP value of 96.76% and 93.37%, as well as low detection limit (0.68 μM and 0.37 μM, respectively). It means that complex 2 had higher selectivity due to the less interference by 4-NT and 2-NP compared with 1. Moreover, the fluorescence quenching phenomenon of sensor 1 with TNP was analyzed by density functional theory (DFT). |
