Open AccessMixed-linker strategy for suppressing structural flexibility of metal-organic framework membranes for gas separation
Structural flexibility is a critical issue that limits the application of metal-organic framework (MOF) membranes for gas separation. Herein we propose a mixed-linker approach to suppress the structural flexib...
