TL;DR: Individual atomically precise polyacetylene chains have been synthesized on a copper surface and characterized using a range of techniques, revealing a doping-induced semiconductor-to-metal transition.

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: This work designed a dihalogenated di( meta-xylyl)anthracene monomer displaying strategic methyl groups at the substituted phenyl ring and investigated its applicability as precursor in the thermally induced surface-assisted polymerization and cyclodehydrogenation.

TL;DR: This work reports a combined in-solution and on-surface synthesis of unsubstituted heptauthrene, whose chemical structure is characterized through bond-resolved atomic force microscopy and its triplet ground state is unambiguously confirmed.

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.
