Abstract

Abstract N-Substituted aminoethyl groups were attached to 1, 4, 7, 10- tetraazacyclododecane-1, 4, 7-triacetic acid (DO3A) with the aim to design pH-responsive Ln III complexes based on the pH-dependent on/off ligation of the amine nitrogen to the metal ion. The following ligands were synthesized: AE-DO3A (aminoethyl-DO3A), MAE- DO3A (N-methylaminoethyl-DO3A), DMAE-DO3A (N, N-dimethylaminoethyl-DO3A) and ...
