Conformationally Switchable Copper(I) Complexes Amplify BODIPY Triplet Photosensitization

open access: yesAngewandte Chemie, EarlyView.
Coupling a structurally switchable Cu(I) complex to an organic light‐harvesting chromophore boosts photoinduced intersystem crossing via the transient formation of a Cu(II) intermediate. Spectroscopic, physical, computational, and photocatalytic studies support this unique new approach to solar energy upconversion.

Radical, Not Ionic: The Mechanochemical Zincke Nitration of Phenols

open access: yesAngewandte Chemie, EarlyView.
Mechanochemistry recasts the classical Zincke nitration as an open‐shell process. Liquid‐assisted vibrational milling of phenols with in situ HNO2 delivers direct and ipso nitration across 50 substrates, while atmosphere, NOx‐transfer, EPR and DFT evidence expose a phenoxyl‐radical/NO2 manifold underlying this historically ionic transformation ...

Efficient Green Light‐Induced Photoclick Reactions Enabled by Triplet–Triplet Annihilation Photon Upconversion

open access: yesAngewandte Chemie, EarlyView.
A general strategy for 9,10‐phenanthrenequinone‐electron‐rich alkene (PQ‐ERA) photoclick reactions via triplet–triplet annihilation upconversion (TTA‐UC) under low‐intensity green light is reported. A TTA‐UC system of PdOEP (sensitizer) and DPA (annihilator) mixed with reactants generates UV/blue photons overlapping the absorption of PQ derivatives ...
