Outline of Final Research Achievements	Synthesis and purification of uranium(IV) and related lanthanide complexes were performed to demonstrate the intense luminescence based on asymmetric design of the molecules. The coordination structure in aqueous solutions was determined by spectroscopic techniques as well as photochemical properties such as energy migration. The experimental results shows spectral change due to the formation of polynuclear species.
