提出了一种基于离子自组装技术，通过简单修饰聚离子液体接枝硅胶相中的抗衡阴离子来设计新型色谱固定相的新策略。以甲基橙子染料作为反阴离子的相对形状受限的异构体表现出超高的选择性。
A new strategy for the design of a new chromatographic stationary phase via simple modifications of the counter anions in poly(ionic liquid)-grafted silica phase based on ionic self-assembly technology is proposed. The phase with methyl orange dye as counter anions exhibits ultra-high selectivity towards shape-constrained isomers.
