Post-synthetic modification of zirconium metal–organic frameworks by catalyst-free aza-Michael additions

UiO-66-NH₂ reacts with acrylonitrile, acrylic acid, methyl acrylate and methyl vinyl ketone leading to post-synthetic modification of the MOF through C–N bond formation. The acrylonitrile-modified MOF undergoes further reaction to form a tetrazolate-modified MOF.
