A porous coordination framework for highly sensitive and selective solid-phase microextraction of non-polar volatile organic compounds

Abstract

A porous metal azolate framework [Zn(mpba)] (MAF-X8, H₂mpba = 4-(3,5-dimethylpyrazol-4-yl)benzoic acid) with large, hydrophobic, one-dimensional channels and good thermal/chemical stability was synthesized and characterized. High-quality MAF-X8 thin films were grown on stainless-steel fibers for solid-phase microextraction (SPME), which showed high sensitivity and selectivity towards non-polar volatile organic compounds.
