| Outline of Final Research Achievements |
For a long time, the field of the molecular magnetism has been developing by precise analysis of the structures for the molecules carrying the spin, using single-crystal X-ray analyses. Therefore, to construct of the gel molecules based on magnetism by using a soft materials of the gel is difficult and is rarely observed in the field of the molecular magnetism. Furthermore, the magnetic interaction between the metal within the gel expected be weaker, therefore, new strategy for the construction of the gel molecules based on magnetism is desirable.
This time, the hetero-spin system consisted of organic spins and metal spins, having the characteristic of a stronger magnetic interaction in addition to flexible structure, is designed and used for the developments of the gel molecules based on magnetism. Furthermore, the responsiveness by external stimuli such as field, using the resulting gel molecules based on magnetism, were investigated in detail.
