Research Abstract

Applying strong magnetic fields(> 10 T) due to superconducting magnet to materials induces huge magnetic field effects(MFEs), in comparison with applying magnetic fields(~ 1 T) due to electromagnet. We attempt to create highly functional nano-materials, since the nanostrutures possessing new physical or chemical properties are constructed by strong magnetic fields. Studying MFEs on photoinduced electron transfer reactions in solutions and photoelectrochemical reactions in photosensitive electrodes is expected to provide useful insights into the complicated reaction mechanisms and thereby to promote research on the application of MFEs in molecular devices. We also examine the MFEs on photoinduced electron transfer reactions and photoelectrochemical reactions using donor-acceptor systems.
