摘　　要：为研究(1S,2R)-(+)-2-氨基二苯基乙醇与对苯二异氰酸酯的二元共聚物和(1S,2R)-(+)-2-氨基二苯基乙醇、对苯二异氰酸酯及对苯二甲酰氯三元共聚物这两种手性固定相所识别手性化合物的结构特点,用一系列手性样品对其分离能力进行了测试,讨论了这两种固定相的构效关系,并用光学纯的手性化合物为标准品,用其混旋体为样品进行分离.结果表明:前一种固定相可用来进行对映体过量的定量分析.To investigate the enantioseparation properties of two chiral stationary phases （CSPs）, which were derived from the copolymerization of （ 1S, 2R）-（ ＋ ）-2-amino-1, 2-diphenylethanol and 1, 4- phenylene diisocyanate; and the copolymerization of （1S, 2R）-（＋ ）-2-aminoq, 2-diphenylethanol, 1,4- phenylene diisocyanate and terephthaloyl chloride, the enantioseparation ability of these two chiral stationary phases were evaluated with a series of chiral analytes. The relationship of structural features between chlral compounds separated and the CSPs were discussed. Using an optically pure chiral compound as the standard, its racemate as the sample, the separation results showed that the CSPs could be applied for quantitative determination of enantiomer excess.
