Metal–organic frameworks have demonstrated great promise for gas separation membranes, but their structural flexibility hinders their stability and hence sieving performance. Here, the authors systematically tune the ratio of mixed linkers in CAU-10-based MOF membranes, finding the optimal ratio that suppresses structural flexibility and enhances CO2/CH4 separation performance.
