| Outline of Final Research Achievements |
Our research group has developed a new series of protic ionic liquids (PIL) comprising such alkyl chelate-amines as alkylethylenediamines and alkyldiethylenetriamines, and then studied the complexations of transition-metal ions in these PILs. The fine structures of the metal complexes in the PILs have been clarified using VIS absorption spectra, NMR relaxations, and EXAFS. It has been revealed that the present PILs are characteristic to encapsulate Lewis acids such as trnasition-metal ions. On the basis of the studies on the interactions with trnasition-metal ions, it has been revealed that the present PILs are advantageous to trap and then release CO2 gas. Furthermore, an effect of the present PILs on the redox behavior of copper(II) ions in imidazolium IL system has been studied.
