Researchers have developed a method to control the opening and closing of pores in metal-organic frameworks (MOFs) by electronically tuning dynamic imine bonds. By adjusting the electronic properties of the imine linkages through chemical modifications, they achieved programmable control over molecular access to the MOF pores. This approach allows for precise gating mechanisms that can selectively allow or block molecules based on size and other properties.


This advancement could enable the development of smart materials for applications in selective gas separation, drug delivery systems, and molecular sensing technologies. The ability to program pore accessibility on demand opens new possibilities for creating responsive materials that can adapt their function to specific conditions or stimuli.
