Abstract Scope Porous Organic Cage (POC) is an emerging class of materials that features high surface area (up to 3758 m2/g) and purely organic composition, which makes it likely to be more compatible with polymer composites such as mixed matrix membranes. Despite its great potential, POC has rarely been used in polymer composites. This lack of representation is likely caused by the poor dispersibility of crystalline POC particles. Although it is possible to improve the dispersibility of POC by scrambling its crystal structure to create an amorphous analogue, we will show in this talk that it is possible to uniformly disperse crystalline POC nanoparticles in a polymer matrix using carefully designed fabrication conditions. The addition of 30 wt% POC nanoparticles improved the CO2 permeability and CO2/N2 selectivity of a Matrimid membrane by 763% and 26%, respectively. This result exceeds the performance improvement reported previously for a Matrimid composite membrane with amorphous POC.
