Abstract Advancing anhydrous proton‐conducting materials is essential for the fabrication of high‐temperature (>373 K) polymer electrolyte membrane fuel cells (HT‐PEMFCs) and remains a significant challenge. Herein, halogen‐bonded organic frameworks linked by [N···I··N] + interactions are reported as outstanding conductive materials. By incorporating carbazole groups into monomers, two highly crystalline ( XOF‐CSP/CTP ) constructed. These XOFs exhibit high intrinsic conductivity (σ = 1.22 × 10 −3 S cm −1 under conditions. Doping with H 3 PO 4 allows nitrogen sites I on pore walls to stabilize tightly confine network within porous framework through hydrogen bonding, thereby enhancing proton conditions 1.02 −2 ). Temperature‐dependent curves theoretical calculations indicate that transport governed low‐energy barrier hopping mechanism. excellent stability maintain across broad temperature range. This work provides new platform designing potential exchange membranes.

Precise and efficient management of disulfide bonds will offer multiple merits for the development organosulfur chemistry, pharmacology, life sciences. However, current S–S coupling synthesis strategy encounters bottlenecks in conforming to separation products, which limits its industrial-scale application. In view superoxide radical-triggered reaction mechanism coupling, this study demonstrates a multifunctional situ-assembled 0D/1D S-scheme heterojunction photocatalyst (MAPB-T-COF) constructed by MAPbBr3 quantum dots imine covalent organic framework (COF) nanowires under guidance band engineering management. MAPB-T-COF exhibits superior photocatalytic performance conversion 4-methylbenzenethiol (4-MBT) p-tolyl (PTD) blue LED illumination. Specifically, it achieves an impressive 100% yield with record photon efficiency as high 12.76%, well universal availability various derivatives, rivaling all incumbent similar systems. This not only highlights effectiveness nanoscale photocatalysis but also perfect trade-off between efficiencies strong chemical redox potentials. addition, free radical that triggers was monitored situ electron paramagnetic resonance (EPR) instrument, provided meaningful insights into mechanism. may inspire photoelectric devices, photoelectrodes, photocatalysts utilizing nanoscale, low-dimensional heterojunctions.
