substituents were synthesized. The propoxy-bound helical PBA shows an excellent chiral recognition as a chiral stationary phase (CSP) in liquid chromatography and resolves various chiral aromatic/aliphatic alcohols. Such powerful CSPs can be produced from the racemic monomer-based PBA via deracemization of the biaryl units.
合成了带有不同取代基的轴向手性2-芳基
吡啶基-N-氧化物单元的单手螺旋聚(联芳基
乙炔)(PBA)。丙氧基结合的螺旋 PBA 作为
液相色谱中的手性固定相 (C
SP) 显示出出色的手性识别能力,并可拆分各种手性芳香族/脂肪族醇。这种强大的 C
SP 可以通过联芳基单元的去消旋化,由基于外消旋单体的 PBA 生产。
