Abstract A series of novel triazole derivative pyridine-based polyamino–polycarboxylate ligands has been synthesized for lanthanide complexation. This versatile platform of chelating agents combines advantageous properties for both magnetic resonance (MR) and optical imaging applications of the corresponding Gd 3+ and near-infrared luminescent lanthanide complexes. The thermodynamic stability constants of the Ln 3+ complexes, as ...
