Abstract

Abstract : A heterometallic MOF probe with the advantages of strong fluorescence, simple synthesis, high density of Lewis acidic and basic sites, and repeatable use, has been designed and synthesized, which exhibits a rapid and sensitive reaction to nitenpyram. Abstract : By employing a mixed metal synthesis strategy, a heterometallic MOF, [In3 Tb3 O3 (TATAB)4 (H2 O)6 ]·12DMF·12H2 O (1 ), has been constructed based on a nitrogen-rich ligand 4, 4′, 4′′- s -triazine-1, 3, 5-triyltri- p -aminobenzoic (H3 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 μg mL −1 .
