Porous Metal-Organic Frameworks have been considered as potential materials for solid state hydrogen storage in recent times. In this context their properties like high permanent porosity, large surface area and the ease of chemical modification due their modular assembly are highly attractive. Unfortunately these materials suffer from low physisorption interaction energies with hydrogen and consequently the need for low adsorption temperatures (77 K) to achieve sufficient hydrogen loadings. One possible approach to overcome the outlined problem is the introduction of unsaturated metal sites within the interior MOF surface to strengthen the adsorbate-adsorbent interaction. We established the functionalization with lithiumalkoxide groups via a post-synthetic transformation of pendant hydroxyl groups with a suitable lithium base. Our results show a significant increase of the isosteric heat of adsorption for hydrogen within the lithium-containing material, thus showing that our approach is a promising strategy to make hydrogen storage in Metal-Organic Frameworks more efficient.
