Dendritic Molecular Magnets: Magnetic Properties as a Function of Structure

由于分子磁团簇是单分子磁体的关键，因此分子磁团簇的合成是非常有必要的。为了设计这样的分子，人们需要知道合适的合成路线以及构建单元对所得到的分子簇的结构和电子性质的影响。在这方面特别感兴趣的是构成构件的参数与分子团簇的磁性之间的相关定量相关性。在这一应用中，提出了一种实验和理论相结合的方法来解决这一领域的开放问题。为了产生新的分子磁团簇，将开发一种树枝状方法，并将合成允许验证相关关联的模型化合物。理论工作将致力于阐明与新合成的化合物和已建立的关联式相关的模型体系的电子和磁性。

The synthesis of molecular magnetic clusters is highly desirable, since they are the key to single molecular magnets. In order to design such molecules one needs to know suitable synthetic route and the influence of the building units on the structural and electronic properties of the resulting molecular cluster. Of particular interest in this respect are relevant quantitative correlations between the parameters of the constituting building blocks and the magnetic properties of the molecular cluster. In this application both an experimental as well as a theoretical approach is proposed to tackle the open questions in this field. To generate new molecular magnetic clusters a dendritic approach will be developed and model compounds will be synthesized that allow the verification of relevant correlations. The theoretical work will be dedicated to the elucidation of electronic and magnetic properties of model systems which are relevant for the newly synthesized compounds and the established correlations.
