Outline of Final Research Achievements

1) To further investigate the characteristic ion exchange properties in phosphoester coordination polymer, XAFS measurement was conducted. It was found that the local structure of not light lanthanide (Ln3+) but heavy Ln3+ is changed when two kinds of Ln3+ coexist in a coordination polymer. 2) Formation of organogels, following lyophilization of phosphoester coordination polymers enhanced the kinetics of ion exchange reaction. 3) Different phosphoesters had some problems, i.e. high solubility in water and low reactivity, therefore they did not offer beneficial information on the relation between the structure and the ion exchange properties. 4) We found that selective ion exchange reaction occurred also in coordination polymers based on carboxylate.
