Deposition of thin films of Ionic Liquids - Access to the IL/Solid-interface — •Michael Stark1, Till Cremer1, Claudia Kolbeck1, Florian Maier1, Peter Wasserscheid2, and Hans-Peter Steinrück1 — 1Lehrstuhl für Physikalische Chemie II — 2Lehrstuhl für Chemische Reaktionstechnik, University of Erlangen-Nuremberg, Egerlandstr. 3, 91058 Erlangen
Ionic Liquids (ILs), salts with melting points below 100∘ C, have attracted a great deal of interest in the last few years due to their promising physico-chemical properties. Important phenomena such as surface passivation, charge transfer and wetting behavior are determined by the IL/solid interface.
To access such interfaces by means of XPS, ultra thin IL films are prepared by physical vapor deposition (PVD) under ultra high vacuum conditions, as has been shown earlier.1
In this study, thin layers of selected ILs were deposited on well defined Au (111) single crystal surfaces in order to obtain a more detailed understanding of IL/substrate interactions. The main aspects thereby are the electronic interactions between the gold surface and the IL and the growth behavior of the films.
This work was supported by the DFG through SPP 1191 "Ionic Liquids" and by the "Cluster of Excellence ’Engineering of Advanced Materials’".
