Functional Organic Nanostructures on Surfaces: Towards Atomically Designed Nanoelectronics, Optoelectronics and Catalysis

Supramolecular chemistry on surfaces [1] – where organic molecules and atoms are used as building units for the assembly of well-defined nanostructures – offers compelling avenues for designing materials with atomic-scale precision and tailored electronic properties. Here, I will focus on one-dimensional (1D) and two-dimensional organic and metal-organic nanostructures, resulting from on-surface interactions between flat aromatic molecules and transition metal adatoms. The local atomic-scale intramolecular morphology, electronic and chemical structure, and electrostatic properties of these systems are characterized by a combination of low-temperature scanning tunneling microscopy and spectroscopy, non-contact atomic force microscopy, X-ray absorption spectroscopy and density functional theory. This bottom-up on-surface synthesis approach offers means for the synthesis of low-dimensional nanostructures with unusual morphologies and properties, that cannot be achieved via conventional synthetic chemistry methods, paving the way for atomically designed materials with novel electronic and catalytic functionalities.
