Two luminescent Zn(II)/Cd(II) metal–organic frameworks as rare multifunctional sensors

Author affiliations


Herein, two new Zn(II)/Cd(II) MOFs, namely {[Zn2(1,4-ndc)2(3-abpt)]·2DMF}n (1) and {[Cd(1,4-ndc)(3-abit)]·H2O}n (2) (1,4-ndc = 1,4-naphthalenedicarboxylic acid, 3-abpt = 4-amino-3,5-bis(3-pyridyl)-1,2,4-triazole, 3-abit = 4-amino-3,5-bis(imidazol-1-ylmethyl)-1,2,4-triazole), based on 3-abpt and 3-abit, respectively, containing the same functional group 4-amino-1,2,4-triazole were synthesized and structurally characterized by single crystal and powder X-ray diffractions, elemental analysis, FT-IR spectroscopy, and TGA. X-ray structural analysis reveals that 1 adopts a 2-D 4-connected net with a Schläfli symbol of (44·62) constructed by flywheel-shaped [Zn2(COO)4] dimeric units, 1,4-ndc single bridges, and double bridges composed of 3-abpt and 1,4-ndc. 2 displays a 3-D 2-fold interpenetrated six-connected architecture with a Schläfli symbol of (412·63), fabricated by planar [Cd2(COO)4] dimeric units, 3-abit double bridges, and 1,4-ndc single bridges. 1 and 2 exhibit stronger luminescence as compared to their organic ligands and very rare multifunctional sensing properties. They can selectively and sensitively sense Fe3+ and Al3+ through luminescence quenching and enhancing effect, respectively. Moreover, 1 and 2 show high sensitivity for the detection of TNP than for other nitro aromatics. The mechanisms of 1 and 2 as multifunctional sensors have been preliminarily studied.
