Racemic mixtures of boronic acid-derived salicylidenehydrazone (BASHY) complexes were enantiomerically resolved. The chiroptical properties of the stereoisomers, containing an asymmetric boron as the only stereogenic unit, are translated into mirror-imaged electronic circular dichroism spectra and circularly polarized luminescence (CPL, dissymmetry factors of 3-5 × 10) is observed. The spectral position of the CPL emission is determined by the push-pull character of the dye. These features expand the functional scope of the brightly emitting BASHY dye platform.
外消旋硼酸衍生的水杨醛缩肼（BASHY）配合物混合物被对映体拆分。手性硼作为唯一的手性单元的立体异构体的手性光学性质转化为镜像电子圆二色光谱，并观察到圆偏振发光（CPL，不对称因子为 3-5×10）。CPL 发射的光谱位置由染料的推拉特性决定。这些特性扩展了发光明亮的 BASHY 染料平台的功能范围。
