Hydrogen Atom Transfer Induces Photodegradation in Carbonyl‐Based Multi‐Resonance TADF Emitters

Angewandte Chemie, EarlyView.
Boosting triplet harvesting in N/C═O MR‐TADF emitters unexpectedly induces rapid photodegradation under oxygen‐free conditions. Spectroscopic studies reveal that triplet excited states trigger hydrogen‐atom transfer from solvent to the carbonyl unit, driven by triplet energetics and hydrogen electrophilicity.

Conformationally Driven Dual Fluorescence Properties of Higher Heteroacenes With Periodically Incorporated Boron Atoms

Angewandte Chemie, EarlyView.
We herein report the synthesis of a new heteroheptacene derivative with periodically incorporated six boron atoms. This compound exhibits dual fluorescence attributed to two interconvertible conformers that result from a delicate balance between the extended π‐system and the steric demand of bulky aryl groups attached to the boron centers.

Dibenzazepin‐verbrückte Netzwerk‐Polymer‐Phthalocyanine als abbaubare heterogene Photokatalysatoren

Angewandte Chemie, EarlyView.
Photodynamische Dibenzazepin‐Brücke wurde in Zink‐ und Kobalt‐Netzwerk‐Polymer‐Phthalocyanine (NP‐Pcs) eingeführt, um abbaubare heterogene Photokatalysatoren zu erhalten. Zum ersten Mal spielt die Bestrahlung mit Licht eine Schlüsselrolle beim „Design, der Verwendung und dem Abbau” von NP‐Pcs.

A Convenient, Safe, and Atom‐Economical Route to a Large Portfolio of Grubbs‐Type Catalysts for Olefin Metathesis via Four‐Coordinate Ruthenium Alkylidynes

Angewandte Chemie, EarlyView.
It may seem counterintuitive to first target a ruthenium alkylidyne when Grubbs‐type ruthenium carbene complexes are the actual goal. In the end, however, this tactic pays valuable dividends in terms of practicality, atom economy, flexibility as well as safety: the new route provides ready access to a large assortment of catalysts for alkene metathesis
