The construction of complex, functional molecules undoubtedly serves as a guiding vision for researchers in the field of nanosciences, not least since Feynman's famous statement "There is plenty of room at the bottom...". The atomic control of the molecular structure allows a direct influence on the properties of a material. In particular, functional materials on surfaces offer access to molecule-based functional devices such as graphene nanoribbons, which are already being used in prototype field-defect transistors. Other potential applications include quantum structures or topological insulators.


Since the deposition and positioning of molecular structures on surfaces for e.g. functional assemblies is difficult, nanostructures are nowadays increasingly successfully fabricated directly on surfaces; this is called "on-surface synthesis". This approach is of particular interest for two-dimensional (2D) materials, which per se require a surface as a support structure. The selective synthesis of such complex functional elements, however, still poses a particular challenge. While synthesis in solution can draw on almost 200 years of experience and perfected methods, the concepts of on-surface synthesis are still in their infancy. The two-dimensional (2D) nature of the surface opens up special opportunities to control reaction processes and offers to selectively build nanoarchitectures from atomic/molecular building blocks.


Our objective within the LOEWE focus group "PriOSS - Principles of On-Surface Synthesis" is to develop fundamental mechanistic models of surface-assisted synthesis and ultimately to create a new toolbox for this methodology, as it has existed for classical synthesis in solution for centuries. Therefore, we would like to bring together researchers with different expertise from the fields of physics, chemistry, and theory.
