	abstract = {<p>Here, we report on a novel class of fluorofoldamer-based artificial water channels (AWCs) that combines excellent water transport rate and selectivity with structural simplicity and robustness. Produced by a facile one-pot copolymerization reaction under mild conditions, the best-performing channel (AWC ) is an n-CH-decorated foldamer nanotube with an average channel length of 2.8 nm and a pore diameter of 5.2 {\r A}. AWC demonstrates an ultrafast water conduction rate of 1.4 {\texttimes} 10 HO/s per channel, outperforming the archetypal biological water channel, aquaporin 1, while excluding salts (i.e., NaCl and KCl) and protons. Unique to this class of channels, the inwardly facing C(sp2)-F atoms being the most electronegative in the periodic table are proposed as being critical to enabling the ultrafast and superselective water transport properties by decreasing the channel{\textquoteright}s cavity and enhancing the channel wall smoothness via reducing intermolecular forces with water molecules or hydrated ions.</p>
