Red Multi‐Resonant Thermally Activated Delayed Fluorescence Emitters as Bioimaging Agents

Advanced Optical Materials, EarlyView.
Multi‐resonant thermally activated delayed fluorescence (MR‐TADF) emitters have attracted strong interest for use in electroluminescent devices due to their high photoluminescence quantum yield and narrowband emission. These properties, along with red emission, are also crucial for bioimaging probes.

Chiral Sensing of Amino Acids under Visible Light via Hydroxypropyl Cellulose Gels

Advanced Optical Materials, EarlyView.
Hydroxypropyl cellulose gels enable visible‐light‐based chiral detection of amino acid enantiomers. This study showcases their structural color properties for distinguishing phenylalanine and alanine enantiomers. The gels exhibit pH‐responsive color changes, high sensitivity at low concentrations (0.2 wt.%), and long‐term stability, offering ...

Enzymatic Asymmetric Synthesis of All Stereoisomers of Aliphatic, Vicinal Diols in Conventional and Non‐Conventional Media

Advanced Synthesis &Catalysis, EarlyView.
Abstract Chiral, vicinal diols are of high interest for academic research and industrial applications. For synthesizing chiral diols, enzymes are important catalysts due to their high selectivity and ability to work under tolerable temperature and no pressure.

Structure‐Guided Engineering of Oleate Hydratase for the Synthesis of Small Chiral Alcohols without Decoy Molecule

Advanced Synthesis &Catalysis, EarlyView.
Abstract Small and chiral secondary alcohols are sought‐after compounds that are frequently used in the synthesis of biologically active compounds. However, their stereochemically correct synthesis remains a challenge for the chemical industry. Synthetic routes are restrained by multiple steps and thus low atom efficiency.

Photoinduced Catalytic Alkylation of Active Methine Compounds with Nonactivated Alkenes Using Yttrium Triflate as a Lewis Acid Catalyst

Advanced Synthesis &Catalysis, EarlyView.
Abstract Photoinduced catalytic alkylation reactions of active methine compounds with nonactivated alkenes have been developed using an organophotocatalyst, a metal Lewis acid, an arylthiol, and an amine base catalyst system. The alkylation reactions proceeded smoothly under ambient conditions with blue light irradiation, affording the desired products

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.
