Understanding charge- and mass-transport processes in two-dimensional covalent organic frameworks to design better materials and energy storage devices.
The establishment of local dimensional interconnectivity creates novel interlayer charge transport channels, which significantly improves electron transport efficiency and achieves highly selective gold recovery.
The modulation mechanisms of Na+ within the redox-active sites of the two-dimensional conjugated organic small-molecule 3BQ, and their impact on the initial capacity of a 3BQ cathode for Na-ion batteries, were investigated using first-principles calculations.
In 2D-COFs, fluctuation in interlayer stacking affects the energetic stability, mechanical strength, thermal conductivity and adsorption capacity of the COFs.
We show that macroscopic principles can predict the nanoscale behavior of 2D covalent organic frameworks and that rigid molecular groups may weaken their overall strength by inducing local strain imbalance.
