Abstract:
A three‐dimensional Cd 2+ framework ( 1 ) with wide one‐dimensional hexagonal channels was prepared based on a tripodal tricarboxylate ligand possessing nitrogen donor atoms. The Cd atoms form a chain structure bridged by carboxylates and aqua ligands. Upon Mg 2+ ion capture, the fluorescence emission of this porous material was 5.2 times greater than its Mg 2+ ‐free fluorescence. To the best of our knowledge, such enhancement has not been previously reported for metal–organic framework sensory systems. The sensing performance of 1 is reversible over repeated cycles of Mg 2+ inclusion and release, revealing the reusability of this material. In the presence of other tested metal ions, Mg 2+ ions were selectively detected owing to the operation of this “turn‐on” mechanism. Thus, this platform is a promising sensor material for selective Mg 2+ ion recognition.
