“…The potential of porous materials for extraordinary sorption capacity of CO 2 and I 2 , established them as the most suitable solid materials to physically adsorb CO 2 and I 2 . − Many types of microporous materials have been fabricated so far such as inorganic–organic hybrid porous materials, microporous organic polymers, polymers of intrinsic microporosity, covalent organic frameworks, crystalline triazine-based frameworks, hyper-cross-linked polymers (HCPs), and porous aromatic frameworks. ,, Recently, inorganic–organic hybrid porous materials (HPMs) have pulled much attention owing to their low density, mechanical and thermal stability, and especially good surface area with tunable porosity as promising materials for gas sorption and isolation, catalysis, environment, and drug delivery applications. , It was revealed that the inorganic part provides structural order, thermal stability, and mechanical strength, and the organic part represents good porosity with tunable functionality. However, the challenge lays in fabrication of materials whose porosities remain intact with a sound compactness in structure compatible to a minimum volume with small surface area.…”
