September 2024
A transition metal coordination polymer (CP), [Cd(Hdpcp)] (Cd-CP) was prepared based on 3-(2,4-dicarboxyphenyl)-6-carboxypyridine ligand (Hdpcp), and then its composite Eu@Cd-CP was synthesized by the post-modification through loading Eu ions on Cd-CP. Eu@Cd-CP has outstanding fluorescence stability in aqueous solution with a wide range of pH. Furthermore, Eu@Cd-CP can distinguish sodium salicylate (SS) and sodium dehydroacetate (SA) in some food additives by quenching the characteristic fluorescence of Eu ion.

- - A 2D achiral metal-organic framework (IMU-MOF) was created using a solvothermal method to help distinguish chiral antimalarial drugs, quinine (QN) and quinidine (QD), which are crucial for health.
- - IMU-MOF acts as an ultrasensitive fluorescent probe, achieving detection limits for QN and QD at 4.24 × 10⁻¹⁰ M and 7.54 × 10⁻¹⁰ M, respectively.
- - Enhanced fluorescence in IMU-MOF is attributed to strong hydrogen-bonding interactions with quinine, leading to more efficient energy transfer during the sensing process.
