Abstract

Using gas chromatography, we studied the influence of the nature of substituents in the β-cyclodextrin (CD) molecule on the sorption properties and the possibility of complex formation with the macrocycle of 26 organic compounds (hydrocarbons and alcohols) in binary sorbents based on the smectic–nematic supramolecular liquid crystal 4-(3-hydroxypropyloxy)-4'-formylazobenzene (HPOFAB) and four derivatives β-CD. It has been established that the nature of the substituents in the β-CD molecule significantly affects the manifestation of solvation interactions between LC and macrocyclic additive and, as a consequence, the mesomorphic, sorption, and selective properties of the studied composite sorbents.

摘要

利用气相色谱法，我们研究了 β-环糊精 (CD) 分子中取代基的性质对二元吸附剂中吸附性能的影响以及与 26 种有机化合物（烃和醇）的大环形成络合物的可能性。近晶-向列超分子液晶4-(3-羟基丙氧基)-4'-甲酰基偶氮苯(HPOFAB)和四种衍生物β-CD。已经确定β-CD分子中取代基的性质显着影响LC和大环添加剂之间溶剂化相互作用的表现，从而影响所研究的复合吸附剂的介晶、吸附和选择性特性。
