Lay Summary (English)

Lead
Lay summary
Coordination compounds of platinum find use for example as anticancer drugs, luminescent materials, molecular wires, and pressure sensors. Platinum complexes often have a planar geometry, and this allows for stacking between individual molecules. Interesting properties such as electrical conductivity or color changes as a function of temperature may result from the weak interactions between individual metal complexes along these stacks.Our research has three key goals: (i) to obtain a detailed understanding of weak interactions between platinum metal centers, (ii) to explore the importance of these interactions for the photophysical and photochemical properties of platinum coordination compounds, and (iii) to assess to what extent noncovalent metal-metal interactions may be useful for the controlled assembly of supramolecular structures.This research project is relevant in the greater contexts of materials science and solar energy conversion. We will attempt to develop new photochromic materials for optical information storage, sensor materials for volatile toxic substances, and we will exploit the potential of platinum complexes for photocatalytic production of hydrogen.
