abstract
Two Cd(II) metal-organic frameworks (MOFs), namely, [Cd(L1)(1,4-NDA)] n ( 1 ) and [Cd 2 (L2)(TDCA) 2 (H 2 O) 2 center dot 0.5CH 3 CN] n ( 2 ) (L1 = 1,4-bis(1-(piperidin-4-ylmethyl)-1H-benzo[ d ]imidazol2-yl)butane, L2 = 1,4-bis(5,6-dimethyl-1-(pyridin-4-ylmethyl)-1 H -benzo[ d ]imidazol-2-yl)butane, 1,4H 2 NDA = 1,4-naphthalenedicarboxylic acid, H 2 TDCA = 2,5 thiophenedicarboxylic acid) were synthesized and characterized. 1 exhibits a 3D dia topology and 2 shows an unprecedented 3D new topology, respectively. Both 1 and 2 behave remarkable chemical stabilities and can be used as good fluorescence sensors for the sensing of Fe 3 + with high sensitivity and selectivity. 1 and 2 have shown fluorescent detection capabilities for enrofloxacin and nitrofurazone, which are rarely reported in previous literature. Furthermore, the mechanism of fluorescence quenching was explained. (c) 2023 Elsevier B.V. All rights reserved.
