OLIS DSM 172 CD & CPL用于“含有手性硼作為立體單元的硼酸衍生的亞水楊基腙配合物的圓偏振發(fā)光”
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 × 10–4) 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.
將硼酸衍生的亞水楊基腙(BASHY)絡(luò)合物的外消旋混合物進行對映體拆分。 含有不對稱硼作為唯一立體異構(gòu)單元的立體異構(gòu)體的手性特性被轉(zhuǎn)化為鏡像電子圓二色光譜,并觀察到圓偏振發(fā)光(CPL,3-5×10-4的不對稱因子)。 CPL發(fā)射的光譜位置由染料的推挽特性決定。 這些功能擴展了明亮發(fā)光的BASHY染料平臺的功能范圍。
