"Surface science of organic molecules: architectures, dynamics and properties"

Περίληψη

Anthoula Papageorgiou, Physics Department, Technical University of Munich

I will give a brief overview of my activities in discovery, elucidation and exploitation of surface phenomena. The methodological approach applied integrates a wide range of spectroscopy and microscopy in ultra-high vacuum with theoretical considerations to generate a high degree of precision in the understanding of interfacial reactions at the atomic level. Henceforth the structure function relationships may be deciphered enabling innovative pathways for the bottom-up fabrication of advanced, functional, surface nanoarchitectures.

I will exemplify this approach by focusing in metal-organic species and nano-architectures at well-defined interfaces. I will present the spontaneous formation of molecular networks encompassing both static and dynamic elements. Such networks can be composed from chemically diverse building blocks containing phenols [Nano Lett., 2016, 16, 1884], carboxylic [Angew. Chem. Int. Edit., 2021, 60, 26932] or hydroxamic acids [Angew. Chem. Int. Edit., 2019, 58, 18948]. The static elements of these networks are controlling the orientation and the motion of the dynamic elements, which can be regarded as guests in a host 2D network. The specific interplay of the host network and the substrate can bestow enantiodirected, dynamic anchoring to the guests.
