STM Study of the structural formation of cobalt naphthalocyanine on Au(111) — •Lothar Brosda and Carsten Westphal — Fakultät Physik - Technische Universität Dortmund, Otto-Hahn-Str. 4, D 44221 Dortmund

The class of phthalocyanine (Pc) and its derivates such as naphthalocyanine (Nc) has received considerable attention within the recent years. Especially the tunability of their electrical and optical properties via a central metal atom provides promising results for their integration in organic devices like light-emitting diodes, thin film transistors, solar cells, or single molecule electronic devices. The performance of such a device is particularly dependent on the quality of the self-assembled monolayer (SAM) and the metal-organic interface. Therefore, a detailed knowledge about the adsorption and the structural formation of the molecules on different substrates is required. Here, the CoNc SAMs were prepared via evaporation under ultra high vacuum (UHV) conditions and investigated by means of room temperature scanning tunneling microscopy (RT-STM). On this poster our results of the structural formation of CoNc will be discussed.
