Here a new nanofilm composite (NFC) membrane is demonstrated. A solution-based, nanopore-limited molecular layer deposition (MLD) is conducted on a nanoporous alumina support to fabricate molecular nets as an ultrathin skin layer. Alternating deposition of multi-functional, tetrahedral molecules gives nanometer thick films of three-dimensionally cross-linked organic molecular networks. To achieve high-flux filtration of molecules, it is essential to have ultrathin, net-like membranes with molecular level thickness. Varying the number of deposition cycles enables to control the pore size of the NFC membrane precisely on the molecular level. The formation of molecular nets is a promising strategy to overcome the limitations of the conventional separation membranes.
