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

Abstract

A novel metal-organic framework {[Zn(XL)₂ ](ClO₄ )₂ ⋅6 H₂ 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 3 D 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 1.72 ppm. More importantly, it is rather rare for an MOF-based luminescence probe to serve as a sensor to effectively detect acetylacetone.
