Naphthalocyanine on metal surfaces studied with a variable temperature STM — •Malte Schulte, Ismail Baltaci, Patrick Mehring, and Carsten Westphal — Experimentelle Physik 1, TU Dortmund, Otto-Hahn-Straße 4, 44221 Dortmund, Germany

The class of naphtalocyanine molecules received large attention within the recent years. In particular, the dependence of their geometric and electronic properties on the central metal ion causes high interest. Therefore, their adsorption and structural formation were determined in several studies. Especially their self-assembly on different surfaces was studied at room temperature.
In this study metal free naphtalocyanine (H2Nc) is investigated on metal surfaces at various low temperatures by scanning tunneling microscopy. STM imaging at low temperature allows to increase the resolving of single molecules. The coverage of the studied surface is less than a monolayer H2Nc while analyzing their self-assembly formation.
