Outline of Final Research Achievements

A cyclic coordinate complex was formed in the aqueous solution of mannitol, boric acid and europium chloride. The self-organized product existed in equilibrium and was difficult to be isolated. The cyclic coordinate complex with building blocks was applied to structural analyses of MS and NMR. The cyclic trisspiroboroester structure was confirmed to be like a recycle mark encircling a lanthanoid ion with a symmetry axis C3.
