Abstract

original image

Molecular gas jars: Methane and carbon dioxide can be stored in open-pore van der Waals crystals of tris-o-phenylenedioxycyclotriphosphazene at low partial pressure, whereas hydrogen, nitrogen, and oxygen are selectively excluded. Gas molecules participate in the supramolecular network of weak interactions and reside in the tight nanochannels in close contact with the surrounding aromatic rings (see picture).
