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感应作用，利用普鲁士蓝类配合物合成了十多种新型手性分子磁体，并通过1 3-(R或S之间的反应合成了三维亚铁磁材料。 )-二氨基丙烷、锰离子和铬离子通过加热在二维亚铁磁体中发生可逆相变。此外，在30℃下，在相同材料中观察到可逆脱水反应，材料转变为三维亚铁磁体，并且当氨基丙氨酸与过渡金属结合时，成功构建了三维手性亚铁磁材料。彻底用于手性有机配体，从化学（新化合物合成）和物理（磁性、结构）的角度推进了最重要特征的手性磁性结构的澄清研究。通过(4,6,7)和中子衍射分析证明(5)该晶体在转移温度以下的磁空间群仍然属于手性磁空间群。
