Abstract

<abstract abstract-type="main" id="bkcs10087-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p id="bkcs10087-para-0001">A fluorine‐functionalized HKUST‐1 (HKUST‐1‐F) has been synthesized by a solvothermal 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 postsynthetic 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.</p> </abstract>
