摘要: 设计合成了新的噻吩杂环衍生化β-环糊精手性固定相2,6-二-O-戊基-3-O-[(2-甲酰基)-噻吩基]-β-CD, 研究了色谱分离性能. 结果表明, 该固定相对各类有机化合物, 特别是芳香族位置异构体及对映异构体有较好的分离能力, 并对含多手性中心的菊酸衍生物具有一定的分离效果, 显示了较强的立体选择能力.

Abstract: A new thiophene heterocyclic β-cyclodextrin derivative, 2,6-di-O-allyl-3-O-[2-(prop-1-en-2-yl)thiophene]-β-CD(GCPS1), was prepared and used as a GC stationary phase. It’s separability for some benzenic isomers and pyrethroic derivatives enantiomers was studied. The result shows that the separation for some benzenic isomers is better than that in the literature. And in meanwhile, four chiral pyrethroic derivatives can be separated well on the column where GCPS1 was used as the gas chromatography stationary phase.

Key words: β-Cyclodextrin derivative, Thiophene, Gas chromatography stationary phase, Isomer separation
