Formula: C10H20O5In 2020 ,《Facilitate Gas Transport through Metal-Organic Polyhedra Constructed Porous Liquid Membrane》 appeared in Small. The author of the article were Deng, Zheng; Ying, Wen; Gong, Ke; Zeng, Yu-Jia; Yan, Youguo; Peng, Xinsheng. The article conveys some information:
Type II porous liquids are demonstrated to be promise porous materials. However, the category of porous hosts is very limited. Here, a porous host metal-organic polyhedra (MOP-18) is reported to construct type II porous liquids MOP-18 is dissolved into 15-crown-5 as an individual cage (5 nm). Both the mol. dynamics simulations and exptl. gravimetric CO2 solubility test indicate that the inner cavity of MOP-18 in porous liquids is unoccupied by 15-crown-5 and is accessible to CO2. Thus, the prepared porous liquids show enhanced gas solubility Furthermore, the prepared porous liquid is encapsulated into graphene oxide (GO) nanoslits to form a GO-supported porous liquid membrane (GO-SPLM). Owing to the empty cavity of MOP-18 unit cages in porous liquids that reduces the gas diffusion barrier, GO-SPLM significantly enhances the permeability of gas.

1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5) is a member of crown ether Ligands. Crown-ethers are macrocyclic polyethers capable of forming host-guest complexes, especially with inorganic and organic cations. Crown-ethers can incorporate protonated primary amine compounds by formation of ion-dipole bonds with the oxygen atoms of the chiral selector. Crown-ethers have been widely used for the separation of several pharmaceuticals both in aqueous and non-aqueous media. Formula: C10H20O5
