A Water-Stable Zn-MOF Used as Multiresponsive Luminescent Probe for Sensing Fe 3+ /Cu 2+ , Trinitrophenol and Colchicine in Aqueous Medium.

A water-stable Zn-MOF was constructed based on H 2 PBA and 1, 10-phenanthroline under solvothermal conditions. The compound exhibited a 3D (2,3,8)-connected (4 3 ) 2 (4 6 .6 6 .8 15 .12)(8) topology framework. The crystal structure and phase purity of the compound was verified by single crystal X-ray diffraction. Subsequently, some studies on the morphology, structure, and luminescent properties were carried out. The results showed that this compound could be used as a versatile chemosensor for Fe 3+ /Cu 2+ , trinitrophenol and colchicine via a luminescence quenching effect in an aqueous medium.
