Abstract
A metal-organic framework-based mesh-adjustable molecular sieve (MAMS) exhibiting a temperature-dependent mesh size. The MAMS comprises a plurality of metal clusters bound with a plurality of amphiphilic ligands, each ligand comprising a hydrophobic moiety and a functionalized hydrophilic moiety, and wherein the metal clusters and amphiphilic ligand functionalized hydrophilic moieties form a metal cluster layer, the metal cluster layer forming at least one hydrophilic pore. On each side of the metal cluster layer, a plurality of associated amphiphilic ligand hydrophobic moieties cooperate with the metal cluster layer to form a tri-layer and a plurality of tri-layers are packed in a facing-spaced apart relationship to form at least one hydrophobic pore.
