Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Shields up!</bold> Post‐synthetic modification of the secondary building units in the metal–organic framework UiO‐66 (Zr₆O₄(OH)₄(O₂CR)₁₂) by dehydration and subsequent grafting of LiO<italic>t</italic>Bu (see picture, green) yields a solid Li⁺ electrolyte with a conductivity of 1.8×10⁻⁵ S cm⁻¹ at 293 K. As the grafting leads to screening of the anionic charge, the activation energy for ionic conduction is significantly lower than when Li⁺ is introduced through deprotonation.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1zt96tc9" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
