The overall aim of this programme is to explore synthetic routes to producing magnetically cooperating systems based on molecular entities and to investigate their structures and properties. Previous work in this group has shown how it is possible to use templating ligands to produce zero dimensional, cluster based systems as well as extended networks of interacting individual paramagnetic centres in one, two and three dimensions. Furthermore, we have recently begun to explore the creation of specified supramolecular and/or synthon organised arrays of the zero dimensional systems which offer possibilities for processing superparamagnetic particles into films or networks of various dimensionalities. This will allow for the creation of cooperative interactions amongst individual high ground state spin particles in a controlled and monodispersed system. This is turn will enable the development of the theory used to describe such systems, which will be carried out in cooperation with the group of Professor Roberta Sessoli in Florence.

该计划的总体目标是探索合成路线，以生产基于分子实体的磁合作系统，并研究其结构和特性。该小组先前的工作已经表明，如何使用模板配体来产生零维、基于簇的系统以及在一维、二维和三维中相互作用的单个顺磁中心的扩展网络是可能的。此外，我们最近已经开始探索创建指定的超分子和/或合成子有组织的阵列的零维系统，这提供了可能性，超顺磁性粒子加工成膜或网络的各种维度。这将允许在受控和单分散系统中的各个高基态自旋粒子之间产生协同相互作用。这反过来将使用于描述这种系统的理论的发展，这将与佛罗伦萨的Roberta Sessoli教授小组合作进行。
