摘要：

Shields up! 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 LiOtBu (see picture, green) yields a solid Li+ electrolyte with a conductivity of 1.8×10-5S cm-1 at 293K. 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. © 2013 WILEY-VCH Verlag GmbH & Co.
