On-Surface Synthesis on Insulating Substrates — •Angelika Kuehnle — Physical Chemistry, University Mainz, 55099 Mainz, Germany

On-surface synthesis has attracted great attention in recent years due to its promising potential for creating functional structures directly on surfaces [1]. An exciting aspect of on-surface synthesis is the capability to arrive at thermally stable molecular structures that might not be accessible by solution chemistry. Using tailored building blocks allows for tuning the electron transport properties of the resulting structure. Especially the latter is of tremendous interest when considering future applications in the field of molecular electronics. Having molecular electronics applications in mind requires decoupling of the electronic structure of the molecular network from the underlying support surface. Thus, it is highly interesting to transfer on-surface synthesis strategies from metallic to insulating surfaces. In this talk, recent results in on-surface synthesis on an insulating substrate carried out in ultra-high vacuum are reported [2-4].
