Spin‐Correlated Luminescence of Mechanically Generated Radical Species

Angewandte Chemie, EarlyView.
A mechanofluorochromic tetraarylsuccinonitrile derivative substituted with bulky triarylmethane groups was synthesized. The mechanochemically generated radical showed red emission and a magnetic field effect on luminescence. ABSTRACT A tetraarylsuccinonitrile (TASN) derivative (12) substituted with bulky triarylmethane groups dissociated into ...

Chiral Heptagon‐Embedded Double [6]Helicenes via Scholl Reaction

Angewandte Chemie, EarlyView.
One bond makes the difference–two chiral and twisted polycyclic aromatic hydrocarbons (PAHs) show different emission behavior. The more flexible one (top) shows a double emission with one having a large anti‐Stokes shift. The two peaks are assigned to different conformers of one and the same compound.

Sequential Homo‐ and Hetero‐Coupling of Isocyanide and Carbon Monoxide Mediated by Acyclic Imino(silyl)Silylene

Angewandte Chemie, EarlyView.
We demonstrate the sequential reactions between an imino(hypersilyl)silylene and aryl isocyanide or carbon monoxide as a molecular‐level model of the Fischer–Tropsch process, providing systematic and detailed insight into C–C bond formation during the homologation of C1 building blocks.
