Energy transfer luminescence of Tb3+ complexed with oxyethylene compounds containing xanthene

Article abstract of DOI:10.1246/cl.1996.547

Three polyether compounds (1-3) which have more than two fluorescent moieties in the both terminals were synthesized, and their complexation properties with Tb³⁺ were discussed. After formation of complex with Tb³⁺, sharp fluorescence lines were observed at visible region due to intramolecular energy transfer from xanthene chromophore to bound Tb³⁺. The correlation between energy transfer efficiency and ligand structure for three analogous compounds were investigated.
