Research Abstract

Magnetism had been recognized as a unique characteristic of inorganic compounds such as metals and metal oxides. Because bulk magnetic ordering is closely correlated with the arrangement of open-shell molecules in the molecular crystal, supramolecular design techniques such as hydrogen bond is successfully applied to construct spin networks.
