Rhodium‐Catalyzed Intermolecular Arylative [2 + 2 + 1] Annulation–Oxidation to Produce Electron‐Deficient Azulene‐Embedded Polycyclic Aromatic Hydrocarbons

Angewandte Chemie, EarlyView.
The synthesis of electron‐deficient azulene‐embedded polycyclic aromatic hydrocarbons has been achieved by the rhodium‐catalyzed intermolecular arylative [2 + 2 + 1] annulation of teraryl diynes with dialkyl acetylenedicarboxylates followed by oxidation at room temperature.

Rotlicht‐vermittelte Erzeugung von Radikalen: Anwendung in Organischer Synthese, Aktivierung kleiner Moleküle, Polymerisierungen und Bio‐bezogener Fachbereiche

Angewandte Chemie, EarlyView.
Die mit sichtbarem Licht betriebene Photochemie hat erhebliche Fortschritte gemacht und bietet vielfältige Methoden für die synthetische organische Chemie. Die Photokatalyse mit rotem und nahinfrarotem‐Licht (NIR) ist aufgrund der geringeren Energie, der reduzierten Phototoxizität, der minimierten Nebenreaktionen und des tieferen Eindringens in ...

Lignin Dissolution and Direct Ultrasmall‐Lignin‐Nanoparticle Formation in Acidic and Alkaline Deep Eutectic Solvents: A Molecular‐Level Insight

Angewandte Chemie, EarlyView.
Structural interpretation and molecular dynamics simulations reveal how molecular moieties and interaction networks influence the π–π stacking structures and conformational states of lignin during dissolution and aggregation: laterally shifted in deep eutectic solvents, offset‐stacked in tetrahydrofuran, and stretched in dimethyl sulfoxide.

Helicenes with Four Helical Turns: Dimerization of [13]Helicenes to [27]Helicenoids

Angewandte Chemie, EarlyView.
The telephone cord challenge: When a 2‐naphthol‐annulated hetero[13]helicene is oxidatively dimerized, two structurally distinct hetero[27]helicenes (both with four helical turns) are formed. When a racemic mixture of [13]helicenes is dimerized, a (M)‐ and a (P)‐helicene join to form a mixed [27]helicenoid (right), and when an enantiomerically pure [13]

Cooperative Photometallobiocatalysis: Nonheme Fe Enzyme‐Catalyzed Enantioconvergent Radical Decarboxylative Azidation, Thiocyanation, and Isocyanation of Redox‐Active Esters

Angewandte Chemie, EarlyView.
Through the directed evolution of an underexploited nonheme Fe extradiol dioxygenase, we developed a unified cooperative photobiocatalytic strategy to allow for three types of enantioconvergent radical transformations, including azidation, thiocyanation, and isocyanation.

Eine Schnittstelle zwischen B‐DNA und DNA‐Mimikry‐Foldameren

Angewandte Chemie, EarlyView.
Helikale aromatische Oligoamid‐DNA‐Mimikry‐Foldamere, die die Form und Ladungsverteilung von B‐DNA‐Duplexen reproduzieren, wurden mit Hilfe eines neuen Linkers, der sowohl als DNA‐Haarnadel als auch als aromatische Oligoamid‐Einheit dient, mit DNA‐Duplexen verknüpft.

Chiral Selenium‐Integrated Multi‐Resonant Thermally Activated Delayed Fluorescent Emitters Showing Improved Reverse Intersystem Crossing Rate

Angewandte Chemie, EarlyView.
The selenium‐based tBuCz‐DiKTaSe emitter containing a twisted ortho‐disposed tert‐butylcarbazole shows high ΦPL, suppressed ACQ, fast kRISC and is chiral. The OLEDs show high EQEmax and alleviated efficiency roll‐off compared to devices with carbonyl‐based MR‐TADF emitters.
