Polyelectrolyte Grafted MOFs Enable Conjugated Membranes for Molecular Separations in Dual Solvent Systems

Summary: Organic solvent nanofiltration (OSN) is a green and cost-effective technique for valuable small active molecule reclamation from organic solvent systems. To date, it remains challenging to develop highly permeable and precisely sieving nanoporous membranes capable of working with dual solve...
