Embodiments of the present disclosure provide a metal-organic framework composition including a metal-organic framework having an ana topology, the metal-organic framework including one or more metals connected to one or more organic linkers. Embodiments of the present disclosure further provide a method of separating chemical species including contacting a metal-organic framework having an ana topology with a flow of paraffins and separating the paraffins.

Zeolite-like metal-organic frameworks with ana topology

Embodiments of the present disclosure include a metal-organic framework (MOF) composition comprising one or more metal ions, a plurality of organic ligands, and a solvent, wherein the one or more metal ions associate with the plurality of organic ligands sufficient to form a MOF with kag topology. Embodiments of the present disclosure further include a method of making a MOF composition comprising contacting one or more metal ions with a plurality of organic ligands in the presence of a solvent, sufficient to form a MOF with kag topology, wherein the solvent comprises water only. Embodiments of the present disclosure also describe a method of capturing chemical species from a fluid composition comprising contacting a MOF composition with kag topology and pore size of about 3.4 &#x212b; to 4.8 &#x212b; with a fluid composition comprising two or more chemical species and capturing one or more captured chemical species from the fluid composition.

Metal-organic frameworks having a kagome topology

Embodiments of the present disclosure describe a zeolite-like metal-organic framework composition comprising a metal-organic framework composition with ana topology characterized by the formula [M(4, 5-imidazole dicarboxylic acid)X(solvent)]wherein Mcomprises a trivalent cation of a rare earth element, X comprises an alkali metal element or alkaline earth metal element, and solvent comprises a guest molecule occupying pores. Embodiments of the present disclosure describe a method of separating paraffins comprising contacting a zeolite-like metal-organic framework with ana topology with a flow of paraffins, and separating the paraffins by size.

Method using metal-organic framework compositions

Amine groups can be introduced in porous materials by a direct (one pot) or post-synthetic modification (PSM) process on aldehyde groups, and the resulting porous materials have increased gas affinity.
