Emergence of Circularly Polarized Luminescence from Achiral o-Carborane-Based Molecules through Molecular Vibrations Coupled with Intramolecular Charge Transfer in Solid States

Circularly polarized luminescence (CPL) were obtained from achiral molecules through stretching vibration of C 1 –C 2 bond coupled with molecular orientations. It caused molecular symmetry breaking, resulting in intense CPL with a larger g lum value.
