Metal–organic frameworks (MOFs) have shown promising behavior for adsorption cooling applications. Using organic ligands with 1, 2, and 3 phenylene rings, we construct moisture-stable Ni-MOF-74 members adjustable pore apertures, which exhibit excellent sorption capabilities toward water fluorocarbon R134a. To our knowledge, this is the first report of isotherms R134a in MOFs. The patterns these materials differ significantly are attributed to variances their hydrophobic/hydrophilic character associated differences size.
