Benzoyl‐Xanthenoxanthenes: Versatile Chromophores for Light‐Engaging Applications

Angewandte Chemie, EarlyView.
Oxidatively stable benzoyl‐fused peri‐xanthenoxanthene ribbons with NIR emission were synthesized. Their good spectral overlap enabled cascaded Förster resonance energy transfer (FRET) antennae in a nematic liquid crystal phase, achieving directional energy transfer.

A Consistent Approach to One Coordinate Pnictide Moieties M≡Pn− Using PnH2− Salts (M = Zr, Ti; Pn = P, As, Sb).

Angewandte Chemie, EarlyView.
One coordinate pnictide (Pn3− = P, As, and Sb) salts of TiIV and ZrIV were prepared using PnH2− as pnictogen atom transfer from suitable TiII and ZrIV complexes through H2 extrusion. This strategy allows access to unprecedented 3d and 4d terminal stibides, alongside phosphide and arsenide analogues, enabling systematic comparisons across the Pn group ...

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.

Tellurophene‐Induced Triplet–Singlet Spin‐Flip Acceleration: An Advanced Design for Narrowband Organoboron Emitters with Fast Reverse Intersystem Crossing

Angewandte Chemie, EarlyView.
Linking an auxiliary dibenzo[b,d]tellurophene unit markedly accelerates exciton spin conversion in multi‐resonance‐type thermally activated delayed fluorescence emitters. Owing to the heavy‐atom effect of tellurium, the corresponding OLEDs retain remarkably high external electroluminescence quantum efficiencies exceeding 25% even at an exceptionally ...
