ResumoFour MIL-101-type porous coordination polymers were synthesized containing different substituents (–H, –NO2, –NH2, –SO3H) in the ligand and their water sorption properties were investigated. All of the compounds adsorbed huge amounts of water (ca. 0.8–1.2 g g−1) and the adsorbed water can be released at relatively low temperatures (ca. 353 K). In addition, the trapping pressure of water adsorption was found to be controlled by changing the substituents, varying the hydrophobicity of the functional groups.
