Summary: A novel multimode superresolution method was developed to map the structure and measure the energy landscape of single carrier transport along conjugated polymer nanowires. By quenching of local emission and tracking the motion of a single photogenerated hole using blinking-assisted localization microscopy, the method successfully correlated structures with charge transport properties. The efficiency of inter- and intrachain hole transport inside the nanowires was compared, and the depth of carrier traps from torsional disorder and chemical defects was directly measured for the first time.

Summary: The study utilized Eu/Tb mixed-metal organic complexes as nano thermometers to probe the intrinsic temperature of MW-absorbing particles in MW fields, and derived an MW-irradiated energy transfer model to predict the extent of microscopic hot spots. The results show that the MW-induced temperature gradient can be enlarged by increasing MW intensity, dielectric loss, and particle size, while lowered by the increase in thermal conductivity and dielectric loss of the liquid.

Summary: Exfoliating COF-935 into CONs through thiol-ene-induced reaction improves their processability and application performance. The addition of vinylene groups weakens the interlayer interactions, enabling the exfoliation of COFs. The modification degree can be quantitatively controlled by adjusting the feeding ratio, resulting in CONs with reasonable pi-conjugation and short lithium-ion transfer distance. The CON-UV-1 exhibits excellent cycle performance and rechargeability. This research provides a promising strategy for the chemical exfoliation of COFs into nanosheets and promotes their potential applications in energy storage.

Summary: Covalent organic frameworks (COFs) are considered as efficient photocatalysts for hydrogen production from solar light. However, the current synthetic conditions for obtaining highly crystalline COFs are complex and hinder their practical application. This study presents a simple strategy for efficient crystallization of 2D COFs based on the formation of hexagonal macrocycles. The results show that this strategy enables the synthesis of highly crystalline COFs in a short time, while maintaining a high hydrogen production rate.
