Abstract

Abstract : A new class of adsorbents with reversible photo-regulated molecular switches was fabricated and simultaneously realized selective adsorption and efficient regeneration. Abstract : Traditional adsorbents with fixed pore surface properties are unlikely to achieve both selective adsorption and efficient desorption, which are extremely desirable in adsorption processes. Here we report a new class of smart adsorbents by introducing photo-responsive azobenzene derivatives to pore interiors of mesoporous silica. The azobenzene molecules are applied as ON–OFF switches for active sites, and are reversibly regulated by UV/visible light irradiation, thus endowing the adsorbents with unprecedented properties to achieve selective adsorption and efficient desorption.
