Patent ID: 8715395

Claim:
A method for adsorbing hydrocarbons, comprising: contacting the hydrocarbons with fluorinated metal-organic frameworks, wherein the fluorinated metal-organic frameworks comprise: a plurality of metal clusters, each metal cluster comprising one or more metal ions; and a plurality of linking ligands, wherein the linking ligands connect adjacent metal clusters to form a coordination polymer, wherein hydrogen atoms are substituted completely by fluorine atoms in each ligand, wherein the fluorinated metal-organic frameworks have 3-D, 2-D, or 1-D structures, wherein the fluorinated metal-organic frameworks adsorb the hydrocarbons, wherein the clusters are assembled into coordination polymers having a plurality of open-ended, hollow channels and internal cavities with hydrophobic internal areas, and wherein the open-ended, hollow channels and internal cavities are capable of reversibly adsorbing and desorbing gases.
