Abstract

Abstract : The modification of amino groups on the surface of In8 cubic SBUs comprising hydrogen-bonded networks with anACO zeolite-like topology resulted in a great improvement in gas adsorption. Abstract : Based upon the typically hydrogen-bonded network, metal–organic cubes, the amino functional group was first introduced onto the surface of the cube to raise the polarizability of the framework by in situ hydrolysis of the precursor 2-amino-4, 5-dicyanoimidazole (ADCIm) with octahedral In 3+ ions under solvothermal conditions, resulting in a supramolecular network with very high CO2 (135.8 cm 3 g −1 at 273 K/1 atm) and H2 (2.03 wt% at 77 K/1 atm) adsorption capacities and an exceptional thermostability range up to 416 °C.
