摘要：

The one-step microemulsion polymerization and complexation of ultrafine metal-complexing particles containing high densities of 1,4,8,11-tetrazacyclotetradecane ligand is studied. These nanoparticles exhibit a high metal-binding ability and a high selectivity for cupric ions and give access to bimetallic polymer materials with adjustable solubility. Results reveal that the one-step synthesis gives access to nanoparticles with the size and the functionalization range of large dendrimers. Furthermore, the complexation of two metallic cations with easily adjustable ratios and their solubility in both aqueous and organic medium easily modulated by surface coverage is observed.
