  "abstract": "The practical deployment of porous organic polymers (POPs) in gas separation applications remains challenging, in large part due to the limited scalability and time-consuming nature of conventional solvothermal synthesis. Herein, we report a facile and scalable sonochemical approach for the synthesis of POPs from cost-effective monomers. The resulting materials exhibit high BET surface areas of up to 664 m2/g and good CO2 separation performance for both CO2/N2 and CO2/CH4 mixtures. Scale-up to multigram quantities was achieved with a space-time yield more than 50-fold higher than that of conventional solvothermal synthesis. This study therefore provides a time-efficient and scalable synthetic strategy for highly porous POPs for gas separation.",
