【Abstract】 A method for the preparation of p-allylcalix[4] arene coated capillaries was developed. The resulted capillaries were electrophoretically tested using phenol derivatives and showed special selectivity. The capillaries can be used for longer than six months and can offer nearly the same detection sensitivity as uncoated tubes. The replacement of silica hydroxyl by phenolic hydiroxyl groups on the inner surface of the capillaries can efficiently reduee the sharp variations of the electroosmotic mobility, keeping a nearly linear relationship between electroosmotic mobility and pH at PH below 8.更多还原
