Triazatriangulenium (TATA) has been proposed as a platform to controllably attach functional molecules to metallic surfaces. We used a combined low-temperature scanning tunneling and atomic force microscope in ultra high vacuum to investigate this platform on Ag(111) surfaces. The molecule TATA was deposited using electrospray ionization. TATA molecules arrange in a complex pattern comprising ring-like subunits. The underlying intermolecular interactions will be discussed.
