Transition from Kwon [4+2]- to [3+2]-cycloaddition enabled by AgF-assisted phosphine catalysis
Nature CommunicationsPhosphine catalysis generally relies on the potential of carbanion-phosphonium zwitterions that are generated via nucleophilic addition of phosphine catalyst to electrophilic reactants.

Advanced Optical Materials, EarlyView.By combining static and time‐resolved optical, structural, and rheological techniques, we demonstrate that the blue‐shift upon solidification of ethyl cellulose‐acrylic acid mesophases corresponds to the reorientation of cholesteric domains. Modulating the mesophase chain mobility and photopolymerization reaction kinetics enables solid chiral nematic ...

Advanced Optical Materials, EarlyView.A surface passivation strategy using yttrium acetate to suppress Mg ion migration from the ZnMgO electron transport layer is proposed. This treatment restores oxygen vacancies on the ZnMgO surface, enhancing device stability. The Cd‐free quantum dot light‐emitting diodes demonstrate a 65.5% increase in operational lifetime with an external quantum ...

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.
Advanced Photonics Research, EarlyView.Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,

Advanced Synthesis &Catalysis, EarlyView.Abstract Pd‐catalyzed reactions are among the most straightforward and efficient methods to proficiently build Csp2‐Csp2 bonds. Nevertheless, thermal activation remains mandatory in most cases, which may decrease the compatibility with sensitive functional groups.
