Series of Fluorescent Coordination Polymers Exhibiting Structural Evolution and Optimized Selective Ion Detection

Crystal Growth & Design, Journal Year: 2025, Volume and Issue: 25(5), P. 1497 - 1505

Published: Feb. 10, 2025

A series of Zn(II)-H2L (H2L = 3,3′-(9,9-diethyl-9H-fluorene-2,7-diyl)dibenzoic acid) fluorescent coordination polymers were synthesized using a mixed-ligand approach through solvothermal methods, demonstrating structural transition from three-dimensional (3D) to two-dimensional (2D) frameworks. The evolution is driven by the gradational size variation pyridine-based ligands, L1 (9,10-di(4-pyridyl)anthracene), L2 (1,4-bis(pyridyl)benzene), and L3 (4,4′-bipyridine), resulting in distinct spatial packing modes. polymers, designated as {[Zn2(L)2(L1)]}n (1), {[Zn2(L)2(L2)]}n (2), {[Zn2(L)2(L3)]}n (3), feature 3D interpenetrated 2D alternating structures, significantly influencing their properties for ion detection. Notably, compound 3 exhibits marked selectivity sensitivity toward trivalent metal ions (Cr3+, Al3+, Fe3+) with detection limits 0.19 μM Cr3+, 0.30 0.37 Fe3+. This research provides valuable insights into designability metal–organic frameworks advances development MOF-based probes selective detection, highlighting impact systematic adjustments on sensing performance.

Abstract The development of sensitive and simple materials for dopamine detection is crucial advancing diagnostic therapeutic approaches. Copper‐based metal–organic frameworks (Cu‐MOFs) have emerged as competitive candidates sensor design, owing to their tunable electronic properties, structural flexibility, cost‐effective preparation. In this study, four MOFs with copper nodes terephthalate or trimesate linkers are synthesized, both without modulators, investigate the influence synthetic strategies morphological characteristics on performance. Among materials, a non‐modulated, Cu(OH) 2 ‐derived copper‐terephthalate MOF demonstrates exceptional sensitivity detection. Its unique flake‐like morphology mesoporosity significantly enhance charge transfer substrate accessibility, achieving linear range 5 × 10⁻ –0.75 mmol L −1 limit 1.26 nmol —outperforming most reported MOF‐based sensors. These results highlight critical role precise control optimization in tailoring Cu‐MOFs electrochemical applications.
