Procedures are described for the removal of the p-butyl groups from p-tert-butylcalixarene and the introduction of benzoyl, nitro, amino and acrylamido groups to yield a series of mono- and bis-substituted compounds on the "upper rim" with potential possibility to polymerized with other monomers. These compounds have been characterized by IR, 1H NMR, elemental analysis and ESI-MS. As the upper rim of the calixarene, which has the site group of polymerization, can be linked into the chains of the polyimides, the ultimate goal of the project is to find a new application for the well established binding properties of calixarene and to develop polyimides that are suitable for the recovery of metal ions from waste water, gas separation and ion-specific electrodes.
