Abstract

The introduction of aromatic substituents onto the binaphthyl backbone of axially chiral binaphthyl organic fluorophores shifts their circularly polarized luminescence (CPL) wavelengths to higher values and may induce CPL sign inversion. Herein, we succeeded in increasing the CPL wavelength without inverting the CPL sign by introducing an alkenyl group onto the binaphthyl backbone.
