Terpyridine‐Functionalized TentaGel Microbeads: Synthesis, Metal Chelation and First Sequential Complexation

open access: yesMacromolecular Materials and Engineering, 2003
AbstractThe functionalization of polystyrene/poly(ethylene glycol) TentaGel® microbeads (d = 20 μm) with 2,2′:6′,2″‐terpyridine units is described resulting in a material with easily accessible ligands which possess an excellent affinity for transition metal ions. The subsequent loading with different metal ions via metal‐to‐ligand complexation yielded
