NEW-TYPE OF C-PIVOT TRIPODE LIGANDS FOR COMPLEXATION TOWARDS ALKALI-METAL CATIONS

A series of C-pivot tripode ligands containing a 2-methylglycerol unit were newly prepared and their complexation properties towards alkali metal cations were examined by the solvent extraction method and UV sp ectroscopy. These types of compounds possessed a higher extractability than the other type of tripode ligand derived from trimethylolethane. This finding clearly shows that the proper selection of the basic ske letal structure is important for the molecular design of C-pivot tripo de ligands.
