Abstrakt: A series of trinuclear lanthanide circular helicates [Ln 3 L 3 ]Cl 3 have been synthesized via supramolecular subcomponent self-assembly. Photophysical studies demonstrate that the unique helical bis-tetradentate 1,29-dialdehyde ligand L 2- could serve as an effective sensitizer for Sm III , Eu III , Nd III and Yb III ions exhibiting efficient characteristic fluorescence emission because of the shell-type blocking of the ligand, which makes them the first circular helicates exhibiting near-infrared lanthanide fluorescence.
