Highly Efficient Sky‐Blue Perovskite Quantum Dot Light‐Emitting Diodes via Ligand‐Assisted Trap‐State Passivation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Highly efficient sky‐blue LED with EQE of 13.6% is realized through short‐chain ligand tridecylamine treaded perovskite quantum dots, due to the suppressed non‐radiative recombination from the trap state. These results indicate that the ligand with strong affinity can facilitate the surface defects passivation, resulting in enhanced optical properties,

Directed Hole Localization Stabilizing Interfacial Sulfur Species to Boost α‐C–H Activation for Selective Biomass Photo‐oxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Efficient α‐C–H bond activation and directional conversion for selective biomass photo‐oxidation are achieved by integrating polarization and interface engineering strategies in P‐doped ZnIn2S4 polar photocatalysts, which leverage hole localization and stable interfacial sulfur species, endowing bio‐based HMF at 94.4% conversion with 94.5% selectivity ...

Modulating Perovskite Crystallization via Multisite Bonding for Enhanced Solar Cell Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study proposes an innovative multisite bonding strategy to regulate crystallization. By employing bidentate ligands N,N‐diethyl‐1,2‐ethanediamine dihydrochloride (DED) that coordinate with uncoordinated Pb2+ and I− vacancies, while simultaneously forming hydrogen bonds with FA+ ions, this synergistic interaction prolongs the perovskite ...
