Research Abstract |
In this research, the stereoselectivity on syntheses of tris-type aminoacidato complexes with chromiuxn(III) or cobalt(III) ion, their isomerization behavior at solid-state and solution-state, liquid-chromatography (LC) and electrochemical behavior had been studied. Above all, the differences of hydrogen-bonding ability based on Bide-chain of aminoacidato ligands or coordination structure were discussed. Interesting results for the photochemical racemization and ligand-exchange reaction of chromium(III) complexes were obtained, newly. While, development of the stationary phase or ionophore based on the hydrogen-bonding ability of cobalt(III) aminoacidato complexes were also proceeded and the following results were obtained ; (1) routine methods were established in the stereoselective syntheses of cob alt(III) complexes containing both glutamate ligand and the different ones, and the separation and analytical methods for each isomers ; (2) stationary phase modified with complexes were prepared, which were bonded to aminopropyl-bonded silicagel by use of free carboxyl-group on complexes ; (3) LC column, where complexes were directly adsorbed at the surface of silicagel, was prepared ; Further study for the elution behavior of various substances with new LC columns prepared on case (2) or case (3) will be continued. And, Study on the preparation of ionic complexes containing ethylenediamine or oxalate ligand will be also attempted toward the development of useful ionophore for sensor.
