Selective gas adsorption by calixarene-based porous octahedral M32 coordination cages

Chem Commun (Camb). 2022 Dec 8;58(98):13628-13631. doi: 10.1039/d2cc04510a.


Giant octahedral M32 coordination cages were prepared via self-assembly of sulfonylcalix[4]arene-supported tetranuclear M(II) clusters (M = Co, Ni) with hybrid linker based on tris(dipyrrinato)cobalt(III) complexes appended with peripherical carboxylic groups. Due to intrinsic and extrinsic porosity, the obtained solid-state supramolecular architectures demonstrated good performance as adsorbents for the separation of industrially important gases mixtures.
