A ZnII-Based Metal–Organic Framework with a Rare tcj Topology as a Turn-On Fluorescent Sensor for Acetylacetone

A ZnII-based metal–organic framework (MOF) with a rare tcj topology has been solvothermally synthesized and displays relatively good thermal and chemical stabilities. Interestingly, the MOF can sensitively and selectively sense acetylacetone (acac) via a fluorescence enhancement effect with a detection limit of 0.10 ppm and good reusability, which demonstrates the first example of a MOF-based turn-on fluorescent sensor for acac.
