Aim

The workshop provides an introduction for the PhD students of the DRG Priority Program “Coordination Networks: Building Blocks for Functional Systems” to electrical and electrochemical characterization of coordination network compounds prepared as films on surfaces. Conductivity of such compounds is a key parameter for their use in many applications in the area of sensing and energy conversion devices. The workshop program consists of tutorial lectures, some lab demonstrations of equipment and an informal discussion between the participating PhD students and postdocs.

Participates are invited to bring posters with their results and problems in the area of film preparation for electrical and electrochemical measurements to facilitate the discussion.

Content

The workshop will give an introduction in the observation of redox transition in films of coordination network compounds and the assignment of transitions with the help of spectroscopic experiments conducted simultaneously with electrochemical measurements. In this context, references from coordination compounds in solution are important to consider as well as the differences in charge transport, if those centers are assembled to films. Electrical conduction in coordination network compounds is also possible in dry state. For the characterization of electrical and thermal conductivity, a set of powerful methods established in solid state physics can be used to characterize films of coordination network compounds, provides that suitable films can be prepared on test chips. The principle of the methods and the requirements of suitable sample preparation will be highlighted. The workshop program will be concluded by an overview of impedance and NMR methods to characterize ionic conductivity in porous solids.
