A sponge for carbon: A new family of porous materials with tunable gas sorption properties has been prepared by integrating metal carboxylates and boron imidazolates under hydro- or solvothermal conditions. One hydrothermally synthesized phase exhibits very high volumetric CO2 storage capacity of 81 L L−1 (273 K, 1 atm).
