Dendritic Molecular Magnets: Magnetic Properties as a Function of Structure

点击翻译按钮获取中文摘要

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.
