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.

分子磁性团簇的合成是制备单分子磁体的关键。为了设计这样的分子，需要知道合适的合成路线和结构单元对所得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相关的定量相关性的参数之间的构成模块和分子簇的磁性。在此应用中，提出了一种实验和理论方法来解决这一领域的开放问题。为了产生新的分子磁性簇，将开发树枝状方法，并合成模型化合物，以验证相关的相关性。理论工作将致力于阐明与新合成的化合物和建立的相关性相关的模型系统的电子和磁性。
