Interest in organometallic polymers has increased during the last years. The electrical and photophysical properties of this type of compound determine their use in many fields: molecular rods and wires, electronic devices, non-linear-optical materials, liquid crystals.
Therefore, the search for new bridging ligands which allow electronic communication between the metal centers, and the study of the electronic coupling in multimetallic systems has been the focus of many organometallic research groups during the last past years.
In the present project we propose the use of ligands based on N-containing heterobi-aromatic compounds, such as quinoline and quinoxaline. These molecules are potential bridging ligands through the formation of C- and N-metal bonds. We will study their reactivity towards different metals and the degree of electronic communication in multimetallic complexes prepared.
The preparation of homo- and hetero-bimetallic species will be the first step. By using these compounds as building blocks we will try to achieve our ultimate goal: the synthesis of planar transition-metal polymers
