A water‐treatment membrane with ordered, 3D, ionic nanochannels showing high water permeability and ion selectivity is reported by M. Henmi, T. Kato, and co‐workers on page 2238 . The membrane transports larger divalent sulfate ions effectively, while smaller monovalent anions such as chloride and bromide are highly rejected by the membrane. These nanochannels are fixed in the membrane by in‐situ photopolymerization of a thermotropic liquid crystalline monomer, forming bicontinuous cubic structures.
