High‐performance polymeric membranes for gas separation are of interest for molecular‐level separation in industrial‐scale chemical, energy, and environmental processes. To overcome the inherent trade‐off relationship between permeability and selectivity, the creation of permanent microporosity in polymeric matrices is highly desirable because the porous structures can provide a high fractional free volume to facilitate gas transport through the dense layer. Here, recent developments regarding the formation of porous polymeric membranes and potential strategies for pore structure design are reviewed.
