ABSTRACT Detecting antibiotic residues is crucial for monitoring their excessive use in healthcare and agricultural practices. Herein, a new 3D metal–organic framework (MOF) containing {[Cd (bpyp)(sdba)]·DMF·2H 2 O} n ( 1 ) (bpyp = 2,5‐bis (pyrid‐4‐yl)pyridine H sdba 4,4′‐sulfonyldibenzoic acid) has been designed synthesized. MOF displays sensitive detection tetracycline (TCY) with limit of below 7.67 × 10 −6 M an aqueous solution. The mechanism involves competitive absorption between antibiotics, supported by UV–vis spectroscopy fluorescence lifetime measurements. exhibits visible response to TCY under 254 nm UV lamp. applied the quantitative lake water recovery based on sensing platform was 92.26–107.54% RSD (%) less than 4.38%, indicating outstanding reliability.
