| Research Abstract |
Recently, new materials possessing unique elctronic and magnetic properties have been desired, and it is strongly required to establish the guide to design these materials. In this project, some new materials, especially bearing redox funcitnalities such as triarylamine (Ar_3N) and N-oyxl moieties, were synthesized, and their redox properties and spi-spin interactions were estimated.
Anilines substituted by Ar_3N and TEMPO were electro-polymerized to afford electro-conductive polyaniline films on the electrode. These functinalized electrodes are expected to be an electrode in rechargeable batteries.
Redox properties of some TEMPO derivatives were studied under various electrolysis conditions. These compounds are found to be interconverted between N-hydroxyl, N-oxyl and N-oxoammonium, reversibly, and work as effective oxidants of alcohols.
Regulation of spins of stable radical materials is very important to realize organoferromagnetics. We have developed a convenient method to synthesize poly-N-oxyl compounds in which N-oxyl moieties were connected by p-electron systems. Spin-spin interactions were detected by ESR spectroscopy.
