Mechanistische Diversität in der photoangeregten Radikal‐Redoxchemie: Eine kritische Evaluierung

open access: yesAngewandte Chemie, EarlyView.
Für viele prominente Beispiele der Photoredox‐Katalyse wird angenommen, dass sie über die Anregung einer offenschaligen („open‐shell“) Zwischenform des Katalysators ablaufen. Es wird jedoch intensiv darüber diskutiert, ob solche Mechanismen realistisch sind und, falls ja, wie genau sie ablaufen können.

Non‐Covalent PL, CD, and CPL Activation of Linear Aromatic Oligomers within Axially Chiral Aromatic Capsules

open access: yesAngewandte Chemie, EarlyView.
Linear aromatic oligomers display intense photoluminescence (PL), circular dichroism (CD), and circularly polarized luminescence (CPL) properties upon non‐covalent encapsulation by axially‐chiral aromatic capsules under ambient aqueous conditions.

Titanium‐Catalyzed Defluorination of Poly(Vinyl Fluoride) and Poly(Vinylidene Fluoride) Under Friedel–Crafts Conditions

open access: yesAngewandte Chemie, EarlyView.
Cationic titanium sandwich catalysts display exceptional activity in the hydrodefluorination of Csp3─F bonds, in the presence of silanes and aromatic solvents (turnover numbers up to 3000). As a result, they can be used to defluorinate challenging fluoropolymers, such as poly(vinyl fluoride) (PVF) or poly(vinylidene fluoride) (PVDF).

Orchestrating Anion–π+ Interactions to Accelerate Metal‐Free Room‐Temperature Phosphorescence

open access: yesAngewandte Chemie, EarlyView.
Tuning anion–π+ interactions in pyridinium iodide contact ion pairs enables ultrafast metal‐free room‐temperature phosphorescence (540–605 nm) with radiative rates up to 5.2×105 s−1. Strong iodide→π+ charge‐transfer coupling, enhanced spin–orbit interactions, and dynamic ion‐pair organization accelerate intersystem crossing and emission, establishing ...

Farnesyltransferase Enables Modular Assembly of Dual‐Functional Nanobody Conjugates for in Vivo Imaging of Inflammation

open access: yesAngewandte Chemie, EarlyView.
A modular farnesyltransferase‐based chemoenzymatic platform enables fast, site‐specific labeling of nanobodies for PET imaging of inflammation. CD11b‐targeted PET agents selectively image myeloid‐driven inflammation, while CD45‐targeted PET agents provide sensitive whole‐body immune mapping.
