合成了四种配体中含有不同取代基（-H、-NO2、-NH2、-SO3H）的MIL-101型多孔配位聚合物，并研究了它们的吸水性能。所有化合物都吸附了大量的水（约0.8-1.2 g g(-1)），并且吸附的水可以在相对较低的温度（约353 K）下释放。此外，发现水吸附的捕获压力可以通过改变取代基、改变官能团的疏水性来控制。 (C) 2012 Elsevier Inc. 保留所有权利。
Four 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. (C) 2012 Elsevier Inc.
