摘要: A new chromatographic stationary phase has been prepared by cross polymerization between allylsilica and perallyloxycucurbit[6]uril characterized elemental analysis FT-IR spectroscopy. The double endcapping proven to improve the separation efficiency of cucurbituril-based material. first end-capping was carried out when made. second done as final step whole process, use a mixture hexamethyldisilazane (HMDS) trimethylchlorosilane (TMCS) an reagent found better than only HMDS or TMCS. Our shown generally good results in nonpolar polar analytes. This showed even performance commercial C18 for case where hostguest chemistry properly incorporated solute retention.
