Alkenyl/Thiol-Derived Metal-Organic Frameworks (MOFs) by Means of Postsynthetic Modification for Effective Mercury Adsorption

The synthesis of new functionally diverse alkenyl‐derived Cr‐MIL‐101s (MIL=material of Institute Lavoisier) was realized by a novel and convenient postsynthetic modification (PSM) protocol by means of the carboncarbon bond‐forming Mizoroki–Heck reaction. The new PSM protocol demonstrates a broad scope of substrates with excellent tolerance of functionality under mild reaction conditions. Moreover, a new metal–organic framework (MOF) that bears both alkenyl and thiol side chains prepared by means of the tandem PSM method has shown excellent adsorbent ability in removing mercury ions from water. Mercurial temperament: The synthesis of new functionally diverse alkenyl‐derived Cr‐MIL‐101s (MIL=material of Institute Lavoisier) was realized by a convenient postsynthetic modification protocol through the CC bond‐forming reaction (see figure). A MOF that bears both alkenyl and thiol side chains was prepared. It shows excellent adsorbent ability in removing Hg ions from water.
