中文摘要: 本项目在前期研究基础上,拟以儿茶素类化合物为模型分子,通过在MAR 上引入不同结构的咪唑类离子液为功能基,系统研究其对模型分子吸附行为。以多重吸附作用力(范德华力、氢键作用力、偶极力、疏水性作用、π-π作用等)为构效关系研究的切入点,以筛分作用参数、吸附作用参数和吸附/解吸附性能参数为三维变量函数,利用三线性成分分析法揭示其构效关系。本研究可为高选择性、专一性MAR 合成的设计和对目标化合物具有最佳分离效能MAR 的预测和筛选提供理论支持。

英文摘要: Based on our previous study, this program aims to systematically study the adsorption behavior of template molecules on MARs functionalized by ionic liquid. Catechin compounds are intends to be used as template molecules, while a series of novel structure MARs are fuctionalized by introducing imidazole ionic liquids of different structures as functional groups. The method of three linear component analysis are employed to reveal the structure-activity relationship with the multiple adsorption forces (Van der Waals force, hydrogen bond, dipole force, hydrophobic interaction, π-π interaction etc.) as the breakthrough point of structure-activity relationship studies, meanwhile, sieving effect parameters, adsorption functional parameters and adsorption/desorption parameters are used as the three-dimensional variable function. This research can provide theoretical support for not only designing and synthesizing MARs with high selectivity and specificity, but also predicting and screening MARs with the best separation efficiency on target compounds.
