Stabilization of the Benzene Radical Trianion in an Inverse‐Sandwich Yttrium Complex

Angewandte Chemie, EarlyView.
A new type of benzene anion state is born: The unprecedented benzene radical trianion embedded in an inverse‐sandwich yttrium complex was synthesized by a one‐electron chemical reduction of its benzene dianion precursor using potassium graphite in the presence of [2.2.2]‐cryptand.

Dual Circularly Polarized Luminescence from Chiral Boron‐Embedded Polycyclic Aromatic Hydrocarbons

Angewandte Chemie, EarlyView.
Boron‐embedded polycyclic aromatic hydrocarbons featuring an asymmetric boron center coordinated by a proximal P═O group were synthesized. Anthracene‐fused boracyclic derivatives show dual circularly polarized luminescence (CPL) arising from excited‐state P═O⋯B dissociation, which converts point chirality into C−B axial chirality.
