Abstract: Supramolecular chemistry is a new branch of sciences, which deals with the specific recognitions between molecules. The host-guest interactions, which exert by supramolecular compounds, can provide a promising prospect for chromatographic separations with high selectivities. Capillary electrochromatography (CEC) is defined as a very promising micro-separation technique with high efficiency and high selectivity in recent years. As the key component of CEC, the stationary phases have been the research focus of CEC development. This paper reviews the recent progress in supramolecular compounds-based stationary phases (cyclodextrin, calixarene, crown ether and macrocyclic polyamine) for CEC since 1998.

Key words: capillary electrochromatography (CEC), stationary phases , supramolecular compounds
