Chemical Property Change in a Metal-Organic Framework by Fluoro Functionality

Description
A fluorine-functionalized HKUST-1 (HKUST-1-F) has been synthesized by a solvo thermal reaction between copper nitrate and a potassium salt of 2-fluoro-1,3,5-benzenetricarboxylic acid (K[H2BTC-F]). HKUST-1-F shows nearly the same crystal structure as that of UHM-31, a known fluorinated HKUST-1. Because of its reduced surface area, HKUST-1-F takes up smaller amounts of gases (N2, H2, CO2) than UHM-31 at 1 bar. After a water vapor adsorption measurement at 298 K, HKUST-1-F turned into an unknown structure, based on powder X-ray diffraction analyses. HKUST-1-F could be further functionalized with benzylamine in a post synthetic modification; the nucleophilic replacement of the F atom in BTC-F with benzylamine in methylene chloride at room temperature took place in a conversion yield of -38% based on 1H NMR analyses
