Gas adsorption agents particularly for separating H2 from a gaseous phase

摘要

Gas adsorbents comprise at least one paracyclophane (or PCP) derivative, constituted by cyclic oligomers formed of mer-units which are interlinked so as to define a rigid structure with a substantially cylindrical intramolecular cavity. The dimensions of the cross-section of said cavity correspond substantially to those of the one or more types of gas molecules that it is desired to introduce therein.
