Shields up! Post‐synthetic modification of the secondary building units in the metal–organic framework UiO‐66 (Zr 6 O 4 (OH) 4 (O 2 CR) 12 ) by dehydration and subsequent grafting of LiO t 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.
