Prototyping New Carbon Allotropes and Nanographenes: On-Surface Synthesis and Single-Molecule Manipulation
Prof. Dr. J. Michael Gottfried
Philipps - Universität Marburg
Recent advances in on-surface synthesis enable the creation of carbonbased
nanomaterials with atomic precision, revealing novel (opto-)electronic and magnetic properties. We developed strategies for synthesizing nonbenzenoid carbon networks, including the biphenylene network, a metallic carbon allotrope with 4-6-8-membered rings [1]. Additionally, we synthesized tridecacene [2] and pentadecacene [3], the
longest acenes to date, which exhibit open-shell antiferromagnetic
ground states and spin-excitation features.
Finally, we explore nitrogen-doped carbon nanostructures, including
cycloarenes and graphene nanoribbons, showcasing their tailored
properties.
