项目摘要

The subject of this research supported by Grant-in-Aid for Scientific Research (B)(2) is to develop novel organic electron-and ion-conducting materials which are molecularly functionalized by introducing various chemical species which are redox active or interactive with ions.Derivatives of electroacitve, conducting polymers such as polyaniline and polypyrrole were synthesized by introducing electroacitve species such as ferrocene, metal ions and organosulfur moieties. These conducting polymers obtained in this research showed facile electron transfers between the conducting polymer main chains and introduced electroactive species. Furthermore, sulfonated polyaniline with copper ions showed enhanced electrocatalytic activity toward redox reactions of organosulfur compounds such as 2,5-dimercapto-1,3,4-thiadiazole.Thermoresponsive phase transition gels based on N-isopropylacrylamide (NIPA) were prepared for control of redox reactions of a ruthenium complex and catalytic activity of hemi … More n toward the electroreduction of hydrogen peroxide (H_2O_2). It was possible that apparent activity of hemin incorporated into the NIPA gels was controlled by changing temperature to induce the phase transition of the NIPA gels between swollen (at a low temperature) and shrunken (at a high temperature) states.Development of gel electrolytes with high ionic conductivity for lithium rechargeable batteries is another subject of this research. Acrylonitrile gel electrolytes with ion conductivity of more than 10^<-3>S/cm were successfully obtained by elaborately controlling the degree, length and structure of cross-links. Furthermore, by introducing ethylene oxide moiety (-CH_2-CH_2-O-) into methyl methacrylate-based polymer matrix, gel electrolytes which are capable of repressing formation of lithium dendrites at the interface between the gel electrolytes and metallic lithium electrode were obtained. These gel electrolytes are highly promising as an electrolyte for polymer lithium batteries with ultra high energy density. Less
