In the Research Article ( e22746 ), Tatsuya Mori, Tomoyuki Ikai, Katsuhiko Tomooka, Shigehiro Yamaguchi, and co-workers reported chiral boron-embedded polycyclic aromatic hydrocarbons featuring a photodissociative intramolecular P=O···B coordination module. Chirality switching from boron-centered point chirality to axial chirality about the C–B axis produces two emissive excited states, resulting in dual circularly polarized luminescence that responds to the solvent environment.
Mori et al. (Sun,) studied this question.
