Description
Summary:Chiral organic fluorophores have recently received growing interest in the field of chiral photoluminescence. We examined chiral binaphthyl organic fluorophores bearing phenyl substituents, observing that they exhibited fluorescence properties in solution. The sign of circularly polarizsed luminescence (CPL) of binaphthyl fluorophores was controlled by changing the solvent from the weakly polar chloroform to the highly polar dimethylformamide or methanol. Moreover, the CPL behaviour was tailored by introducing phenyl substituents into the binaphthyl unit and by replacing hydroxyl moieties with ethoxy groups.
