| abstract |
Disclosed are chelates resulting from the complexation of bifunctional do2pa derivatives ligands of formula (I), wherein the substituents R1, R1′, R2, R2′, R3, R3′, L1, L1′, L2 and L2′ are defined as in the claims, with metallic cations, especially Pb(II) and Bi(III). Also disclosed are bifunctional do2pa derivatives ligands of formula (I), as well as the use of chelates in nuclear medicine and the use of ligands in cations detection or epuration of effluents. |
