Outline of Final Research Achievements

Luminescent lanthanide (Ln(III)) complexes have shown great interest as candidates for luminescence probes for substrates recognitions such as substrate biomolecules and inorganic anions, because of the unique photo-physical properties of Ln(III) ions including long lifetime and narrow spectra within visible or near-infrared regions. In these system, most of luminescence response derived from formation of association complex with the guest substrate molecules and the host lanthanide complexes.
In this report, we developed the luminescent lanthanide sensors with Ln(III) complexes for multi-point specific molecular recognition in aqueous media. We reported that the development of the cation-anion sensing of Eu(III) complex and the ratiometric anion sensing with mixed-Eu(III)/Tb(III) complex　were successful.
