Abstract
A circularly polarized luminescence (CPL)-active liquefied chiral molecule based on the Schiff-base boron difluoride structure was developed. The introduction of polyethylene glycol (PEG) chains into the Schiff-base ligand lowers the melting point of the molecule allowing the boron complex to be a liquid at room temperature. The complex exhibited blue CPL in the liquid state with absolute luminescence dissymmetry factor (glum) one and a half times higher than in the dilute solution state.

The complex exhibited blue CPL in the liquid state with glum of 2.0 × 10−3.
