Preparation of Novel polyimides Containing Calix4arene

摘要

Two polyimides containing pendant calix[4]arene unit have been synthesized via terminated reaction. The calix[4]arene monomer, which has the site group of polymerization in the upper rim, was linked into the chains of the polyimides. At the same time, the liquid membrane transport of K~+ ions by the two polyamide acid-calixarenes were investigated which testified that the two polyimides containing calix[4]arene have transport ability.
