Gas separation heats up
The polymer can selectively adsorb oxygen over argon, an industrially useful behaviour. It is usually difficult to separate these gases using conventional adsorbents because the gas molecules have similar sizes, shapes and physicochemical properties. Kitagawa believes this work could open up a new field of external-stimuli-responsive porous solids for recognising and separating target molecules.
