By employing a mixed metal synthesis strategy, a heterometallic MOF with high density of metal ions and -NH- sites has been constructed, showing stability and sensitivity in detecting nitenpyram.
By employing a mixed metal synthesis strategy, a heterometallic MOF, [In3Tb3O3(TATAB)(4)(H2O)(6)]center dot 12DMF center dot 12H(2)O (1), has been constructed based on a nitrogen-rich ligand 4,4',4 ''-s-triazine-1,3,5-triyltri-p-aminobenzoic (H(3)TATAB). Compound 1 shows a 3D doubly interpenetrated framework built from dual-walled cages of dimension ca. 2.8 nm. In particular, the framework of 1 possesses a high density of Lewis acidic metal ions and Lewis basic -NH- sites decorated on the pore walls. Fluorescent sensor study indicates that 1 can maintain its stability and agility after several cycles of detecting nitenpyram, and the detection limit of 1 for nitenpyram is as low as 0.17 mu g mL(-1).
