二个 chiral 选购者从酒石的酸被综合。选购者同时在 3-aminopropyl 硅石胶化上被使不能调动获得新 biselector chiral 静止阶段(CSP ) 以便在 chiral 识别能力上决定 biselector CSP 的选购者结构的影响。为比较,单个选购者的 CSP 也被准备。biselector CSP 与单个选购者的 CSP 比较显示出一个改进全面 chiral 识别能力。在 enantioseparation 期间,暂时的 diastereoisomers 被在 chiral analyte 和二个选购者之间的 complexation 多半在 biselector CSP 上形成。在二个选购者的功能的组在电子效果或在为 chiral 识别的位的阻碍者是补足的。
Two chiral selectors were synthesized from tartaric acid. The selectors were simultaneously immobilized on 3-aminopropyl silica gel to obtain a new biselector chiral stationary phase (CSP) in order to determine the influence of selector structure of biselector CSPs on the chiral recognition capability. For comparison, the single-selector CSP was also prepared. The biselector CSP shows an improved overall chiral recognition capability in comparison with the single-selector CSP. During the enantioseparation, temporary diastereoisomers are likely formed by complexation between a chiral analyte and the two selectors on the biselector CSP. The functional groups in the two selectors are complementary in electronic effect and/or in steric hindrance for the chiral recognition.
