A Sensitive Luminescent Acetylacetone Probe Based on Zn-MOF with Six-Fold Interpenetration

A novel metal-organic framework {[Zn(XL)(2)](ClO4)(2)6H(2)O}(n) (XL=N,N'-bicyclo[2.2.2]oct-7-ene-2,3,5,6-tetracarboxdiimide bi(1,2,4-triazole)) was synthesized and structurally characterized, presenting the first example of six-fold interpenetrating 3D framework with the topology type of sqc6, which displays high thermostability and solvent stability. Additionally, the luminescence investigations reveal that this MOF can sensitively and selectively detect acetylacetone with a detection limit of 1.72ppm. More importantly, it is rather rare for an MOF-based luminescence probe to serve as a sensor to effectively detect acetylacetone.
