Porous frustrated Lewis pair catalysts: Advances and perspective

Frustrated Lewis pairs (FLPs), well known for the ability to activate small molecules via the concerted action of Lewis acid and Lewis base, have inspired an ever-widening scope of chemistry. The rapid development of this class of catalysts has promoted research into a promising direction: porous heterogeneous FLP catalysts, which possess several advantages for industrial application, such as controllable synthesis, tunable structure and composition, high surface area with abundant and accessible active sites, efficient mass transfer, and easy separation and reuse. This perspective summarizes recent progresses and provides an outlook in designing porous FLP catalysts for applications in heterogeneous catalysis.
