“…While much progress has been made to improve activation methods of porous materials using ultralow surface tension exchange solvents and supercritical CO 2 , , the reproducible preparation of high surface area materials remains non-trivial. In particular, MOFs with coordinatively unsaturated sites (CUS) are especially difficult to fully activate due to the strong interaction of solvent with the metal centers . Nonetheless, when these strong affinity sites are accessible, the CUS is advantageously employed for selective gas adsorption, , separations, , catalysis, , and in sensing applications. , In addition, the CUS provides potential sites for expanding the chemical functionality of MOFs through grafting. ,, Therefore, efforts to improve the surface area of CUS-MOFs are critical for achieving their full functionality.…”
