Hydrogen-bonded organic frameworks (HOFs) show great potential in energy-saving C2 H6 /C2 H4 separation, but there are few examples of one-step acquisition from because it is still difficult to achieve the reverse-order adsorption and . In this work, we boost separation performance two graphene-sheet-like HOFs by tuning pore polarization. Upon heating, an situ solid phase transformation can be observed HOF-NBDA(DMA) (DMA=dimethylamine cation) HOF-NBDA, accompanied with electronegative skeleton into neutral one. As a result, surface HOF-NBDA has become nonpolar, which beneficial selectively adsorbing The difference capacities for 23.4 cm3 g-1 uptake ratio 136 %, much higher than those (5.0 108 % respectively).

Optimizing the electronic structure of covalent organic framework (COF) photocatalysts is essential for maximizing photocatalytic activity. Herein, we report an isoreticular family multivariate COFs containing chromenoquinoline rings in COF and electron-donating or withdrawing groups pores. Intramolecular donor-acceptor (D-A) interactions allowed tuning local charge distributions carrier separation under visible light irradiation, resulting enhanced performance. By optimizing optoelectronic properties COFs, a uranium extraction efficiency 8.02 mg/g/day was achieved using nitro-functionalized multicomponent natural seawater, exceeding performance all reported to date. Results demonstrate effective design strategy towards high-activity with intramolecular D-A structures not easily accessible traditional synthetic approaches.
