TL;DR: The on-surface synthesis of atomically precise nanographenes and their atomic-scale characterization on a gold substrate by using low-temperature noncontact atomic force microscopy and scanning tunneling spectroscopy clearly reveals the emergence of magnetism in nanographenees and provides an efficient way to further explore the carbon-based magnetism.

TL;DR: In this paper, the authors demonstrate an effective approach of engineering magnetic ground states in atomically precise open-shell bipartite/non-bipartite nanographenes using combined scanning probe techniques and mean-field Hubbard model calculations.

TL;DR: It is demonstrated that metal-free porphyrins host delocalized pi-electron magnetism as revealed by scanning probe microscopy and different level of theory calculations, and can be further extended to design new magnetic functionalities of porphirin-based architectures.

TL;DR: An effective approach of engineering magnetic ground states in atomically precise open-shell bipartite/nonbipartite nanographenes using combined scanning probe techniques and mean-field Hubbard model calculations is demonstrated.

TL;DR: This study's results reveal that quinoid PPP chains adopt a coplanar adsorption configuration on Cu(111), and host in-gap states near Fermi level, indicative of a quasiparticle behavior originating from charge-lattice interactions.
