This invention pertains to adsorption by an adsorbent of an adsorbate and to regeneration of the loaded adsorbent. The adsorption includes contacting an adsorbent selected from arylene-bridged polysilsesquioxanes and derivatives thereof with an adsorbate selected from aromatics and heterocyclics, particularly monocyclic heterocyclics containing carbon and nitrogen atoms in a 6-member non-aromatic ring, for a period of time sufficient to adsorb all or part of the adsorbate by the adsorbent. Regeneration of the loaded adsorbent includes removing all or part of adsorbate from the adsorbent by means of an alcohol wash or by thermal desorption of the adsorbent containing adsorbate.
