中文摘要: 本项目主要利用配位化学方法,构建新型的无机-有机多酸杂化单分子磁体自组装体系。在该体系中,我们拟选择合适的反应条件,选用顺磁性过渡金属离子,稀土离子或三角骨架金属簇,与三脚架有机配体自组装得到多核磁性簇,多核磁性簇通过缺位多酸来稳定其结构,从而构筑结构新颖的多酸无机-有机杂化磁性簇材料, 研究其结构和磁性能,揭示多酸在单分子磁体构筑中的作用与优势,并了解化合物结构与磁性之间的内在联系,探索多酸单分子磁体的重要影响因素和规律。该项目的研究,不仅有利于促进物理,化学,材料学科的交叉,同时也有助于探索新型无机-有机杂化材料的设计与合成。

英文摘要: This project aims at the foundation of novel self-assembly system of inorganic-organic hybrid single molecular magnets by means of coordination chemistry methods. Herein we are going to choose the suitable reaction conditions,select paramagnetic transition metal ions or rare metal ions or triangle metal clusters and tripodal ligands, obtain polynuclear magnetic clusters by self-assembly methods, which are stablized by lacunary polyoxometalates, construct polyoxometalate-based inorganic-organic hybrid magnetic clusters with novel structures, research the structures and magnetic properties, reveal the effect and strength of polyoxometalate on constructing SMMs, understand the intrinsic relations of structure and magnetism, explore the important influences and laws of polyoxometalate-based SMMs. The research is not only helpful for promoting the crossing and blending of physics, chemistry, materials, etc, but also exploring the design and synthesis of novel inorganic-organic hybrid materials.
