Reacting calix[6]arene hexaesters with poly(ethyleneimine), a series of calix [6]amides- based polymers were obtained for the first time. It is found that they show high absorption capacities towards soft cations comparing to hard cations, and the absorption abilities enhanced with the increasing of calixarene content, which may indicates the cavity of calixarene plays crucial role in absorption. Polymer 2c shows good selective absorption capability towards Ag+ among the tested cations.
