Ditopic helicate ligands and were synthesized for the formation of dinuclear Eu luminescent chiral helical assemblies (Eu·L) in competitive organic and protic solvent media. Spectroscopic analysis revealed formation of the 2:3 (Eu·L) and 2:2 (Eu·L) species in methanolic solutions. Circular dichroism and circularly polarized luminescence (CPL) spectroscopy confirmed the chiral purity of the helical systems, while scanning electron microscopy imaging demonstrated the formation of hierarchical self-assemblies with spherical morphologies.

- The study details the creation and evaluation of water-soluble chiral ligands designed for forming structures directed by lanthanide ions, specifically focusing on europium (Eu(III)).
- These ligands, made from pyridine-2,6-dicarboxylic amides with naphthalene groups, were modified to improve their solubility in water and were shown to form chiral complexes with high quantum yields of luminescence.
- The research employed techniques like circular dichroism and fluorescence analysis to track changes during the self-assembly process and determined binding constants, leading to the development of luminescent hydrogels from these ligands and complexes.
