High Free‐Volume Imidazole‐Based Ionomers for High‐Temperature Proton Exchange Membrane Fuel Cells
Advanced Science, EarlyView.High free‐volume imidazole‐based ionomers (PF4IM‐72) enable enhanced phosphoric acid uptake and efficient proton transport, delivering peak power densities of 0.645 W cm−2 at 160 °C and 0.838 W cm−2 at 200 °C in HT‐PEMFCs. This work highlights a promising platform for next‐generation ionomers with improved high‐temperature performance and stability ...

Mixed‐Polymer Hole Transport Layers Reinforce Au‐Anode Top Emitting Perovskite Light Emitting Diodes
Advanced Science, EarlyView.Au‐anode corrosion is shown to occur rapidly under voltage bias in MAPbI3 perovskite LEDs. Resulting Au+ migration quickly leads to device shorting and unstable emission during constant current driving. We demonstrate that using a simple mixed‐polymer hole transport layer containing polyTPD and PVK can reduce Au‐corrosion and stabilize LED operation ...

Donor Extended Blue TADF Dendrimer for High‐Performance Solution‐Processed OLEDs
Advanced Science, EarlyView.A dendronized MR‐TADF emitter, DOBNA‐SpAc‐DCz, was designed to improve solubility, hole transport, and exciton dynamics for solution‐processed OLEDs. Incorporation of ter(tert‐butylcarbazole) dendrons decreases ΔEST and accelerates RISC, yielding short delayed lifetimes (∼2 µs).

Advanced Science, EarlyView.Through a mixed‐ligand strategy that precisely regulates pore size and framework polarity, the Xe adsorption behavior is transformed from flexible to near‐rigid. ZIF‐7‐Cl(20) achieves sensitive recognition, efficient capture, and high selectivity for Xe, enabling high‐efficiency separation from Xe/Kr mixtures.
