What is Systematic Investigation of CO~2~ Adsorption Energetics in Metal–Organic Frameworks Based on Imidazolyl Linkers about?

This study explores system dependence (from the choice of metal and ligand) in the energetics for CO 2 confinement in 3-dimensional (3D) metal-organic frameworks (MOFs) employing imidazolyl ligands, namely, ditopic 2-methylimidazole (HMeIm) in Zn(MeIm) 2 (ZIF-8), Co(MeIm) 2 (ZIF-67), and tetratopic tetrakis(imidazolyl) boric acid (HB(MeIm) 4 ) in CuB-(MeIm) 4 (Cu-BIF-3). All frameworks have a sodalite topology. Direct gas adsorption calorimetric experiments enable quantitation of energetic drive for CO 2 confinement in the frameworks. The general trend in the integral adsorption enthalpy ΔH int (kJ/mol) is Cu-BIF-3 > ZIF-8 > ZIF-67. In ZIFs, greater porosity is consistent with more favorable CO 2 incorporation. Overall, the use of larger linkers in BIFs provides the greatest enhancement of the energetics of CO 2 adsorption in MOFs. The strength of guest-host interactions depends strongly on the choice of linker and metal.
