Efficient metal ion sieving in rectifying subnanochannels enabled by metal–organic frameworks
Open accessAbstract
Biological ion channels have remarkable ion selectivity, permeability and rectification properties, but it is challenging to develop artificial analogues. Here, we report a metal–organic framework-based subnanochannel (MOFSNC) with heterogeneous structure and surface chemistry to achieve these properties. The asymmetrically structured MOFSNC can rapidly conduct K + , Na + and Li + in the subnanometre-to-nanometre channel direction, with conductivities up to three orders of magnitude higher than those of Ca 2+ and Mg 2+ , equivalent to a mono/divalent ion selectivity of 10 3 . Moreover, by varying the pH from 3 to 8 the ion selectivity can be tuned further by a factor of 10 2 to 10 4 . Theoretical simulations indicate that ion–carboxyl interactions substantially reduce the energy barrier for monovalent cations to pass through the MOFSNC, and thus lead to ultrahigh ion selectivity. These findings suggest ways to develop ion selective devices for efficient ion separation, energy reservation and power generation. Here, using an interfacial growth strategy, UiO-66 MOF nanocrystals are asymmetrically embedded into conical pores in a polymer membrane. These pores have a mono/divalent cation selectivity of 10 3 , which can be tuned by pH, and act as ionic rectifiers.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
