Porous Organic Cage Thin Films and Molecular‐Sieving Membranes

A solution-processable dissymmetric porous organic cage

“…Molecular cage compounds 3,4 are attractive materials for membrane applications, in part due to their solution processability, which can be used to tune their porosity by crystal engineering, 5 to deposit them onto a range of substrates, and to blend them with other materials, such as polymers, to form mixed matrix membranes. 6 The porous organic cage (POC) CC3 (ref. 7) shows remarkable hydrolytic stability and can separate noble gases, 4 SF 6 from N 2 , 8 hexane 9 and xylene isomers, 10 and racemic alcohols and amines.…”

Interfacial engineering of renewable metal organic framework derived honeycomb-like nanoporous aluminum hydroxide with tunable porosity

“…1–4 Synthetic methods for preparing porous materials are roughly categorized into two general types, which are recognized as hard-template and soft-template methods. 5 The hard template method, which mainly uses siliceous materials, involves the tedious removal of the framework with a highly corrosive solution, which is dangerous during operation, and is also not applicable in the preparation of materials that are sensitive to acid or alkali.…”

Oriented Two‐Dimensional Porous Organic Cage Crystals

“…Recently, amorphous cage thin films and membranes were fabricated on various substrates by spin coating 13. Uniform and pinhole‐free cage membranes were obtained and demonstrated molecular‐sieving properties.…”
