Abstract:
Polymers and copolymers are derived from substituted macrocyclic metal chelators. These polymers may be cross-linked, and are typically insoluble in most solvents. The metal complexes of these polymers exhibit the useful catalytic activity of the monomers. The polymers are advantageously prepared by reacting a polybasic nucleophile with the substituted macrocyclic metal chelator. Copolymers of the macrocyclic metal chelators with other polyfunctional monomers are also formed by reaction with suitable polybasic nucleophiles. Suitable macrocyclic metal chelators for use as monomers in accordance with the present invention have at least one leaving group substituent which is labile for aromatic nucleophilic substitution and at least one electronegative (or electron-withdrawing) substituent.
