摘要

In the last few decades,coordination compounds which provide diversified and tunable frameworks or electric structures,play a key role in the field of functional materials.The construction of desired assembled structures and the control of their physical properties can be achieved by integrating appropriate constituents with sophisticated designs.Recently,much attention has been devoted to quantum effects and the multifunction of molecule-based magnets in this area.Lanthanide (4f metal) ions are promising components of functional materials because of their large magnetic anisotropy arising from the strong L-S coupling and fluorescent characteristics.
