Keywords: | [No Keyword Available] | Publisher: | Amer Chemical Soc | Abstract: | Biological ion channels use both their sizes and residual groups to reject large ions and molecules and allow highly selective permeation of small species with similar sizes. To realize these properties in artificial membranes, the main challenge is the precise control of both the channel size and the interior at the nanoscale. Here we report the permeation of ions and molecules through interlayer channels in graphene-based laminar membranes. The amino groups decorated on channel walls are found to form hydrogen bond networks with intercalated water molecules, thus providing a highly stable laminate structure and a controlled channel size. Solutes with hydration diameters of >10 angstrom are precisely sieved out. Small species permeate through with selectivities of up to a few thousand, governed by their distinct electrical interactions with channels depending on the atomistic distance from the charged species to the channel walls. Our work offers important insights into manipulating channel structures for enhanced separation performance at the nanoscale. | Description: | Jiang, Yu/0000-0002-6505-4072; Hu, Sheng/0000-0002-1285-6055; yagmurcukardes, mehmet/0000-0002-1416-7990 | URI: | https://doi.org/10.1021/acs.jpclett.2c03579 | ISSN: | 1948-7185 |
