Outline of Final Research Achievements

Some lanthanide complexes which have achiral structures in usual condition show structural change from achiral to chiral structure with the interaction with other chiral chemical species. New chiral sensing systems using this circularly polarized luminescence from the structural changed lanthanide complexes by other chiral species (induced CPL) were studied.
Eu(III) complexes having phenanthroline or bipyridine derivatives were examined as probe molecules of this class of chiral sensing system. It was found that the sensitivity and selectivity of the sensing system is much dependent on the ligands of the probe molecules.　We developed a CPL spectroscopic system which can detect from visible to near-infrared region. This made allow us to examine various chiral sensing probes than previous one. Using this system, we found that metal center of the probe molecules also affect the chiral sensing system in the chiral sensing system of lanthanide complexes of phenanthroline derivatives.
