Reconstructing Quantum Dot Surfaces via Dual‐Functional Ligand Pairing Enables Efficient Shortwave Infrared Optoelectronics

Advanced Functional Materials, EarlyView.
This work presents a ligand‐pairing strategy that reconstructs lead sulfide quantum dot surfaces for efficient short‐wave infrared optoelectronics. A low‐reactivity thiourea precursor combined with hydrobromic acid enables monodisperse and fully passivated quantum dots.

Acid Site Design for Low Hydration Proton Exchange Membranes

Advanced Functional Materials, EarlyView.
α‐CF2 substitution adjacent to sulfonic acid increases acid strength and enables efficient proton transport under low hydration conditions. This molecular design reduces the dependence of hydrocarbon proton exchange membranes on excessive water uptake, addressing a key limitation of conventional hydrocarbon PEMs while maintaining favorable conductivity
