Abstract
For the selective emission of positive- and negative-sign circularly polarized luminescence (CPL), two chiral organic luminophores with opposing chirality are generally needed. In this study, the solution-state CPL sign of an axially chiral binaphthylacetic acid organic luminophore was successfully controlled by changing the solvent from chloroform (or methanol) to dimethylformamide (or acetonitrile).
