The chemistry of artificial 2D atoms implemented at a metal-molecule interface — Aizhan Sabitova^1,2, Jeffrey Rawson^3,4,2, Ruslan Temirov^1,2, and •F. Stefan Tautz^1,2 — ¹Peter Grünberg Institut (PGI-3), Forschungszentrum Jülich, Germany — ²Jülich Aachen Research Alliance (JARA), Fundamentals of Future Information Technology, Jülich, Germany — ³Peter Grünberg Institut (PGI-6), Forschungszentrum Jülich, Germany — ⁴Institute of Inorganic Chemistry, RWTH Aachen, Germany

Localising the hybrid metal-molecule interface state of PTCDA/Ag(111) at artificially patterned vacancies we form atom-like structures whose electronic states exhibit well-defined angular momenta, giving rise to direction-specific bonding interactions. These two-dimensional artificial atoms can be constructed into multinanometer-scale molecules whose wavefunctions exhibit features, such as sigma and π-bonding configurations, previously only attributed to natural molecular orbitals.
