项目摘要

Over ten new chiral molecule-based magnets were synthesized by the Prussian Blue type complexes by using the chiral induction by the organic chiral ligands. Two dimensional ferrimagnetic and the three-dimensional ferrimagnetic materials were synthesized by the reaction among 1 3-(R or S)-diaminopropane, manganese ion and chromium ion. The reversible phase transitions was fond in the two dimensional ferrimagnet by heating at 30 ℃. Moreover the reversible dehydration reaction was observed in the same material and the material was transition to three dimensional ferrimagnet. Moreover, the combination of the transition metals succeeded in the construction of the three-dimensional chiral ferrimagnetic material when the amino alanine was thoroughly used for the chiral organic ligand. The clarification research on Chiral magnetic structure that was the most important feature was advanced from the viewpoint of the chemistry (new compound synthesis) and physics (magnetic, structural analysis). It is proven (5) that the magnetic space group below the metastasis temperature of this crystal is affiliated with the Chiral magnetic space group still by (4,6,7) and the neutron diffraction.

利用有机手性配体的手性诱导作用，通过普鲁士蓝型配合物合成了十余种新型手性分子基磁体。利用1-（3-（R或S）-丙二胺与锰离子和铬离子反应合成了二维和三维亚铁磁性材料。在30 ℃加热时发现二维亚铁磁体存在可逆相变。此外，在相同的材料中观察到可逆的脱水反应，并且材料转变为三维亚铁磁体。此外，当氨基丙氨酸被充分用作手性有机配体时，过渡金属的组合成功地构建了三维手性亚铁磁性材料。从化学（新化合物合成）和物理（磁性、结构分析）的角度对手性磁性结构这一最重要的特征进行了澄清研究。通过（4，6，7）和中子衍射证明（5）该晶体在转移温度以下的磁空间群仍属于手征磁空间群。
