A Versatile Tripodal Ligand for Sensitizing Lanthanide (LnIII) Ions and Color Tuning

A versatile ditopic ligand system for sensitizing the luminescence of bimetallic lanthanide bio-imaging probes.

The homoditopic ligand 6,6'-[methylenebis(1-methyl-1H-benzimidazole-5,2-diyl)]bis(4-{2-[2-(2-methoxyethoxy)ethoxy]ethoxy}pyridine-2-carboxylic acid) (H(2)L(C2)) has been tailored to self-assemble with lanthanide ions (Ln(III)), which results in the formation of neutral bimetallic helicates with the overall composition [Ln(2)(L(C2))(3)] and also provides a versatile platform for further derivati...

Unsymmetrical tripodal ligand for lanthanide complexation: structural, thermodynamic, and photophysical studies.

Two tridentate and one bidentate binding strands have been anchored on a carbon atom to provide a new unsymmetrical tripodal ligand L for Ln(III) coordination. The ligand itself adopts a single conformation in solution stabilized by intramolecular hydrogen bonds evidenced in the solid state. The reaction of L with trivalent lanthanides provides different coordination complexes depending on the ...

Fine-tuning of lanthanide-monocarboxylate coordination networks through ligand decoration.

We report herein five new coordination polymers of general formula [LnNa(C(6)H(5)CO(2))(4)] where Ln = Y (6), Tb (7), Er (8), [DyNa(CH(3)CO(2))(4)(MeOH)] (9) and [DyNa(C(3)H(7)CO(2))(4)] (10). Single crystal structure analyses revealed that all compounds have a repeating unit containing one Ln(3+), one Na(+) and four monocarboxylate ligands (RCO(2)(-)) (R = -CH(3), -C(3)H(7), -C(6)H(5)). Compou...
