项目摘要

Polynuclear cages of paramagnetic transition metal ions can exhibit fascinating physical properties and have great potential in the field of single molecule magnetism and molecular spintronics. Supramolecular chemistry is defined as chemistry beyond the molecule, and involves (amongst other things) the design of molecular building blocks for the construction of novel structures that can be polymeric or discrete in nature. We recently discovered a range of new polynuclear cages that have interesting magnetic properties and that act as Single-Molecule Magnets or Molecular Refrigerants (molecules that cool themselves down when a magnetic field is applied to the material). We intend to marry these cluster types with new and large scale molecular building blocks to afford novel discrete and polymeric superstructures. The resulting materials will have tailored magnetic properties (depending on the cluster type we choose to incorporate) and we will explore the ability of these assemblies to play host to guest molecules (e.g. by the passage of molecules through pores in infinite structures containing voids, or in individual cavity containing molecules). The storage and separation of important gases within all of the materials to be synthesised (either organic or metal-organic) will be studied in collaboration with Prof. Andrew Cooper, head of the Centre for Materials Discovery at the University of Liverpool.Dr. Scott J. Dalgarno has expertise in calixarene synthesis and crystallographic studies on large supramolecular polynuclear metal cluster systems. Dr. Euan K. Brechin is a world leader in molecular magnetism and polynuclear metal cluster synthesis. These synthetic and analytical techniques will be critical in elucidating the structures and properties of the materials to be formed, and have already allowed us to determine the magnetic properties of the aforementioned metal clusters that display Single-Molecule Magnet or Molecular Refrigerant behaviour to underpin the work proposed here.

顺磁性过渡金属离子多核笼子在单分子磁性和分子自旋电子学领域具有广阔的应用前景。超分子化学被定义为超越分子的化学，涉及(除其他外)设计分子构建块，以构建性质上可以聚合或离散的新结构。我们最近发现了一系列新的多核笼子，它们具有有趣的磁性，可以充当单分子磁体或分子制冷剂(当磁场施加到材料上时，分子会自我冷却)。我们打算将这些团簇类型与新的和大规模的分子构建块相结合，以提供新的离散和聚合超结构。得到的材料将具有定制的磁性(取决于我们选择合并的团簇类型)，我们将探索这些组装件作为客体分子宿主的能力(例如，通过分子通过包含空洞的无限结构中的孔，或在包含分子的单个空腔中)。将与利物浦大学材料发现中心主任安德鲁·库珀教授合作，研究所有合成材料(有机材料或金属有机材料)中重要气体的储存和分离。斯科特·J·达尔加诺在杯芳烃合成和大型超分子多核金属簇合物体系的结晶学研究方面拥有专业知识。尤安·K·布雷钦博士是分子磁学和多核金属簇合成领域的世界领先者。这些合成和分析技术将对阐明将要形成的材料的结构和性质至关重要，并已使我们能够确定上述金属团簇的磁性，这些金属团簇表现出单分子磁体或分子制冷剂行为，以支持这里提出的工作。
