Organic Molecules on Insulating Surfaces: From Self-Assembly to On-Surface Synthesis
Molecular self-assembly has proven to be a most versatile tool for creating functional structures on surfaces . So far, the majority of studies has been performed on metallic substrates, and comparatively little is known about molecular structure formation on wide band gap insulators. However, molecular self-assembly on insulating surfaces can be fundamentally different from structure formation on metallic substrates due to the comparatively weak molecule-surface interaction. Consequently, special strategies have to be developed for anchoring organic molecules onto insulating surfaces . Upon balancing the interplay between intermolecular and molecule-surface interactions, a rich variety of molecular structures can now be achieved at room temperature [3,4].
When aiming at creating application-relevant structures, thermal stability and a significant electron transport can be mandatory. Recently, on-surface synthesis has been identified as a promising strategy for arriving at covalently linked organic structures at surfaces. Transferring these design principles to insulating surfaces allows for further enhancing the structural flexibility on application-relevant substrates [5,6].
