Deskripsi

Biological cell membranes can efficiently switch Na+/K+ selectivity in response to external stimuli but achieving analogous functions in a single artificial membrane is challenging. Here, the authors report highly crystalline covalent organic framework membranes with well-defined nanochannels and coordinative sites that act as ion-selective switches to manipulate Na+ and K+ transport.
