It is challenging to introduce pendent sulfonic acid groups into modularly built crystalline porous frameworks for intrinsic proton conduction. Herein, we report the mechanoassisted synthesis of two sulfonated covalent organic (COFs) possessing one-dimensional nanoporous channels decorated with groups. These COFs exhibit high conductivity as 3.96 × 10(-2) S cm(-1) long-term stability at ambient temperature and 97% relative humidity (RH). In addition, they were blended nonconductive...
Abstract Additives treatment is as a very effective strategy to optimize bulk heterojunction (BHJ) morphology. However, the inherent working mechanism of this still lacks systematical investigations in non‐fullerene‐acceptors‐based organic solar cells (OSCs).

Abstract Blade‐coating which is compatible with roll‐to‐roll (R2R) fabrication has been considered a promising technology for the large‐scale production of organic solar cells (OSCs).

We propose an efficient approach to expand the COF repertoire by introducing high-valency quadrangular prism (D4h ) node connectivity eight, based on which two...

Proton exchange membrane fuel cells (PEMFCs) have achieved milestones in performance improvements and commercial launches. In the typical commercialized PEMFCs, compressed air to cathode is usually supplied from ambient air, assuming that no costly pre-purification system applied.
