A Tb (Ⅲ) Coordination Polymer Based on 5-(2-(Pyrazole-1-yl) Pyridine-5-yl) Terephthalic Acid and Its Visual Detection of Quinolone Antibiotics.

ABSTRACT: The abuse of quinolone antibiotics in the medical and livestock industries potentially causes environmental accumulation that may impair ecological stability. Based on the organic ligand 5-(pyrazole-1-yl) pyridine-5-yl) terephthalic acid (H₂PPIPA), a terbium(III) complex, [Tb(HPPIPA)(PPIPA)(H₂O)]ₙ (complex 1), was synthesized via solvothermal reaction with Tb(NO₃)₃·6H₂O. Luminescence studies revealed that complex 1 functions as a turn-on fluorescent probe for the selective detection of ofloxacin (OFX), levofloxacin (LFX), and norfloxacin (NFX), with detection limits of 27.9, 17.1, and 8.0 nM, respectively. Owing to its high selectivity and anti-interference capability, the complex was successfully applied for the determin
