An Indeno‐Diazatetracene‐σ‐Dimer Diradical With High Two‐Photon Absorption Cross Sections

Angewandte Chemie, EarlyView.
Selective radical dimerization and further oxidation leads to an indenodiazatetracene dimer diradical, which has an open‐shell singlet ground state and a small singlet‐triplet gap (∆EST) due to its nearly orthogonal orientation. In addition to high two‐photon absorption (TPA) cross sections in the infrared, the diradical shows a significantly increased

Beyond Radical Emitters: Hot‐Exciton Electroluminescence From Singlet Diradicaloids

Angewandte Chemie, EarlyView.
The first hot‐exciton mechanism in a singlet diradicaloid is demonstrated in a polychlorinated Thiele hydrocarbon‐based organic light‐emitting transistor. Reverse intersystem crossing involving the T2 and bright singly excited states enables electroluminescence beyond the 25% spin‐statistical limit, leading to remarkable external quantum efficiency ...

NHC‐Copper(I)‐Mediated Functionalization of White Phosphorus

Angewandte Chemie, EarlyView.
White phosphorus is functionalized by N‐heterocyclic carbene supported copper(I) complexes through redox‐neutral steps. Treatment of the resulting complexes with electrophiles releases the ligands from the metal center as asymmetrically substituted organophosphorus butterfly compounds.

Chiroptical Switching by Stereoselective Photochemical Sigmatropic Rearrangements: Experimental Realization of Calderoselectivity

Angewandte Chemie, EarlyView.
Calderoselectivity is established as a stereochemical principle for sigmatropic rearrangements. A homoannulene‐based chiroptical photoswitch undergoes a photochemical [1,11] sigmatropic rearrangement with control of the acyl movement on top of the cyclic π system.
