Photocatalytic Cross‐Coupling of Phenols and Heteroaryl Halides With Machine Learning‐Guided Reaction Prediction

Angewandte Chemie, EarlyView.
Photocatalytic cross‐coupling: A redox‐neutral photochemical method enables direct C(sp2)─C(sp2) bond formation between phenols and heteroaryl halides using an organic dye and base. Complementary radical generation allows efficient cross‐coupling in up to 91% yield. Mechanistic studies, DFT, HTE, and machine learning rationalize and predict reactivity,

Out‐of‐Equilibrium Supramolecular Assembly Sustained by Photocatalysis

Angewandte Chemie, EarlyView.
Catalysis sustains structure: A Pt(II) supramolecular photocatalyst persists in a far‐from‐equilibrium state only as long as it remains photocatalytically active. Without ongoing catalytic activity, the system irreversibly relaxes into a thermodynamically stable but inactive state (PtB). Catalysis is essential for sustaining its structure.

Dibenzazepine Bridged Network Polymeric Phthalocyanines as Degradable Heterogeneous Photocatalysts

Angewandte Chemie International Edition, EarlyView.
Dibenzazepine photodynamic bridge has been introduced to zinc and cobalt networks phthalocyanines (NP‐Pcs) to obtain degradable heterogeneous photocatalysts. For the first time, light irradiation plays a key role in “design, use and degradation” of NP‐Pcs.
