| 摘 要： | 杯芳烃(Cahixarenes)是一类由苯酚单元经亚甲基相连而成的大环化合物，与β-环糊精类似，它能与多种溶质形成主客体包容配合物，并通过超分子作用识别离子和中性分子等客体，利用杯芳烃的分子识别作用可提高色谱分离性能，Glennon等制备了酯化杯[4，6]芳烃键合固定相，

| Abstract: | A calix[8]arene-bonded gel silica stationary phase(DCABS) was prepared by using coupling reagent(KH560). Its structure was characterized by FTIR, elemental analysis and thermal analysis. The chromatographic performance of DCABS was studied by using different solutes as probes and stationary phases as reference. The results show that the new material has an excellent reversed-phase chromatographic property. The new bonded phase can provide various sites for analytes, such as the hydrophobic interaction, hydrogen-bonding, π-π, electrostatic interactions. Meanwhile, it was observed that the chromatographic performance of DCABS is partially different from CABS because of elimination of the butyl groups. |
