A novel series of ligand bearing three to six pendant 2,2′-bipyridine groups attached to acyclic (tripode, tetrapode) and macrocyclic (cyclam, hexacyclen) polyamines has been synthesized and shown to form metal complexes, in particular of polynuclear type.
The Eu3+ complexes of the tripode and tetrapode ligands 1 and 2, respectively, containing2,2′-bipyridine coordinating units have been prepared. The UV absorption and luminescence spectra, lifetimes, and quantum yields have been measured under a variety of experimental conditions. The contributions of different paths to the decay of the luminescent excited state are evaluated, and the structures of

been developed for the preparation of ligands bearing two to six pendent, unsubstituted or substituted 2, 2′-bipyridine groups attached to acyclic (tripode, tetrapode) and macrocyclic (triazanonade-cane, cyclam, hexacyclen, bis(bipyrido)hexaazamacrocycle) polyamines. Ligands 1-5 have been obtained in high yield by condensation of 6-(bromomethyl)-2, 2′-bipyridine (9b) with the corresponding amines in
