Enhanced Amplified Spontaneous Emission from Optically Pumped Perovskite Light‐Emitting Diodes with Sodium Fluoride Additives

Advanced Photonics Research, EarlyView.
This study investigates sodium fluoride (NaF) as an additive in halide perovskite films to improve their optical and light amplification properties for application in laser diodes. The incorporation of NaF leads to a threefold increase in light‐emitting intensity and a 20% reduction in the amplified spontaneous emission (ASE) threshold, along with ...

PTC in the Polyenolate‐Mediated [10+2]‐Cycloaddition for the Synthesis of α,α‐Disubstituted Amino Acid Precursors

Advanced Synthesis &Catalysis, EarlyView.
Abstract The manuscript describes a formal [10+2] higher‐order cycloaddition between 2‐arylideneindan‐1‐ones and α‐alkylidene azlactones as higherene precursors and higherenofiles respectively. The reaction is realized under Brønsted‐base catalysis utilizing the phase transfer catalysis approach.

Double‐Sided Control of Product Type Preference in the Visible‐Light Initiated Reaction of 1,3‐Dicarbonyl Compounds with Alkenes

Advanced Synthesis &Catalysis, EarlyView.
Abstract The demonstrated light‐initiated addition of radicals formed on an active methylene group to styrene derivatives exhibits a product selectivity influenced by the presence of a protic solvent. Under protic conditions, the predominant products are branched compounds with the alkene moiety attached to the methylene group.

Constant enzymatic in situ production of H₂O₂ for an Unspecific Peroxygenase by an L‐amino acid oxidase

Advanced Synthesis &Catalysis, Accepted Article.
Unspecific Peroxygenases have been the subject of a lot of research in the recent past as they offer opportunities for green hydroxylation reactions using hydrogen peroxide (H₂O₂) as donor. A striking problem of UPOs is their low stability against their own co‐substrate H₂O₂.
