Ultrafast rectifying counter-directional transport of proton and metal ions in metal-organic framework–based nanochannels

Science Advances, Journal Year: 2022, Volume and Issue: 8(14)

Published: April 6, 2022

Bioinspired control of ion transport at the subnanoscale has become a major focus in fields nanofluidics and membrane separation. It is fundamentally important to achieve rectifying ion-specific artificial channels, but it remains challenge. Here, we report previously unidentified metal-organic framework nanochannel (MOF NC) nanofluidic system unidirectional ultrafast counter-directional alkaline metal ions proton. This highly effective behavior attributed two distinct mechanisms for proton, elucidated by theoretical simulations. Notably, MOF NC exhibits proton conduction stemming from ultrahigh mobility, i.e., 11.3 × 10-7 m2 /V·s, low energy barrier 0.075 eV MIL-53-COOH subnanochannels. Furthermore, shows excellent osmotic power-harvesting performance reverse electrodialysis. work expects inspire further research into multifunctional biomimetic channels advanced nanofluidics, biomimetics, separation applications.

Fluorescent materials presenting unique color changes in response to external stimuli have wide applications information storage and anticounterfeiting. However, developing intelligent fluorescent with high security levels dynamically displaying encrypted is still a challenge. Herein, we report new method for constructing excellent by loading the photochromic molecule spiropyran into lanthanide metal-organic framework.

As irradiation time extended, continuously from yellow-greenish orange then red through FRET process within 60 s. This composite system has great potential anticounterfeiting because following advantages: (1) different emissions optical colors regulated ultraviolet radiation, which convenient designing complex patterns; (2) can be repeatedly verified quickly exhibit dynamic s, having advanced anticounterfeiting, where key encryption/decryption. These advantages will greatly enhance reliability measures increase difficulty

The evolution of the chemical and pharmaceutical industry requires effective less energy-intensive separation technologies. Engineering smart materials at a large scale with tunable properties for molecular is challenging step to materialize this goal. Herein, we report thin film composite membranes prepared by interfacial polymerization porous organic cages (POCs) (RCC3 tren cages). Ultrathin crosslinked polycage selective layers (thickness as low 9.5 nm) are obtained high permeance strict sieving nanofiltration. A dual function achieved combining catalysis. This demonstrated impregnating highly catalytically active Pd nanoclusters ( ~ 0.7 nm). While membrane promotes precise separation, its catalytic activity enables surface self-cleaning, reacting any potentially adsorbed dye recovering original performance. strategy opens opportunities development other different functions well-tailored abilities.
