Direct Observation of Li+ Ions Trapped in a Mg2+lated Metal-Organic Framework

Abstract

Herein we report the first example of a metal-organic framework (MOF) in which the location of Li+ ions trapped in the porous confinement can be unambiguously defined by single-crystal X-ray diffraction. Furthermore, the Li+-doped MOF shows significant enhancement in gas uptake as well as selective adsorption of CO2 over CH4
