Research Abstract

We aimed at developing novel functional coordination nano-clusters. We have succeeded in synthesizing several single molecule magnets. They are dodecanuclear MnFe complexes with wheel structure, tetranuclear MnFe complex with arch structure, and tetranuclear NiFe complex with square structure. Moreover, we have succeeded in synthesizing a photo-tunable one-dimensional homo-chiral MoCu complex. These materials can be used as components of future high density recording devises.
