Outline of Final Research Achievements |
Electrochemical control of liquid/liquid distribution of ionic species through specific interactions with the dendrimer and application of photofunctionalized dendrimers as a spectrophotometric reagent were studied by means of spectroelectrochemical techniques. The mechanistic analysis of charge transfer reactions across the liquid/liquid interface demonstrated that the encapsulation behavior of ions into the dendrimer significantly depends on the molecular size and charged state of the dendrimer. It was also indicated that the axial-coordinations of the dendrimer to the metal center of encapsulated species could enhance the ion association stability. In addition, the photofunctionalized dendrimers obtained from the hybridization with luminescent gold nanodots and chemical modifications were examined as separation and spectrophotometric reagents for metal ions in liquid/liquid systems.
