Partitioning / Self‐assembly of Artificial Water Channels – Toward Controlled Permselectivity through Bilayer Membrane

Year: 2024

Type: article

Abstract: Artificial water channels (AWCs) have been extensively explored to mimic natural proteins, which enables to effectively transport water while blocking ions. As one of the first AWCs, self‐assembled I‐quartets (HCx) have showcased high water‐permselectivity that can be enhanced by improving their distribution and stability within membrane. The use of long alkyl chains (n>8) is constrained by their low solubility and aggregation. Herein, we considered cycloalkyl moieties, explored for the increase of the solubility favoring enhanced partition and/ for their self‐assembly behaviors resulting the formation of effective stable water‐channels with increased water permeability in bilayer membranes. This class of cycloalkyl‐ureido‐ethyl‐imidazole amphiphilic (CxUH) channel could serve as a new reference for the effective design of self‐assembled artificial water channels, it may give rise to the applications in desalination or in water treatment.
