Abstract:

Molecular separation is one of the most energy-intensive industrial processes, primarily due to the inadequate efficacy of current separation methods. This issue becomes critical when it comes to large polymeric compounds. Our group has been focusing on developing new technologies for separating polymers using crystalline nanoporous media, metal–organic frameworks (MOFs). We recently made a discovery that MOFs can adsorb polymers in their nanopores. During the adsorption process, even the slightest differences in polymer structures are recognized, enabling highly precise polymer separation. This has allowed us to distinguish the differences in terminal groups, topology, and even monomer sequences of polymers, which were previously impossible using conventional methods.
