Hidden Diradical: Conformational Switch for Solvatochromic NIR Emission With Unity Quantum Yield in Thiele's Hydrocarbon

Angewandte Chemie, EarlyView.
Halogen substitution controls a conformational switch between a folded closed‐shell and a flat singlet‐diradical conformer in an air‐stable Thiele‐diradical. This conformational switch allows for near‐unity photoluminescence quantum yield with a large Stokes shift, solvatochromism, and a long‐lived excited state.

Twist and Shine: The Impact of Halogen Substitution on Thiele Hydrocarbon's Optical Properties

Angewandte Chemie, EarlyView.
Halogenation in Thiele hydrocarbons strongly influences structure and excited‐state dynamics. Depending on substitution, “boat” folded forms show large Stokes shifts and strong solvatochromism, while planar “butterfly” derivatives exhibit near‐unity photoluminescence yields.

50 Years of Giese Reaction – a Personal View

Angewandte Chemie, EarlyView.
The Giese‐Reaction celebrates its 50. Birthday, it is a cyclic radical chain reaction centered around C,C‐bond formation in a three component synthesis. This minireview speaks about the birth of the name‐reaction, explains how the complete understanding of its reaction mechanism stimulates new methods in organic synthesis, and why it can proceed in ...

A Precisely Bromo‐Functionalized [9]Cycloparaphenylene as a Platform for Late‐Stage Multisite π‐Extension Toward Chiral Nanohoops

Angewandte Chemie, EarlyView.
Precisely synthesized hexabrominated [9]cycloparaphenylene (CPP), accessed by a gold‐mediated method, enables efficient multisite post‐functionalization through cross‐coupling reactions. Late‐stage π‐extension on the CPP framework successfully affords armchair‐type chiral nanohoops exhibiting strong circularly polarized luminescence (|glum| = 0.100 ...

Predictive, Data‐Driven Design of Red‐Light Photoredox Catalysts for C─Heteroatom Bond Formation

Angewandte Chemie, EarlyView.
From redox numbers to red light: Donor oxidation and core reduction potentials predict E0‐0 in cyanoarene dyes, guiding selection of an efficient red‐light catalyst, 4MeODPATPN (PC13). Under 620 nm light, PC13 facilitates Ni‐catalyzed C─heteroatom cross‐couplings (C─N, C─O, C─S) with high functional‐group tolerance and reduced hydrodehalogenation ...

Synergistic Effects of Electricity and Light for Efficient Iron‐Catalyzed Recycling of Polystyrene Waste

Angewandte Chemie International Edition, EarlyView.
The synergistic interplay of electricity, light and earth‐abundant, nontoxic iron catalysis allowed for the efficient recycling of post‐consumer polymers into value‐added products. This robust depolymerization strategy was viable on multigram‐scale, where the cathodic hydrogen evolution reaction presents an attractive opportunity for a green hydrogen ...
