Kekulene: On-Surface Synthesis, Orbital Structure, and Aromatic Stabilization.
Anja Haags,Anja Haags,Alexander Reichmann,Qitang Fan,Larissa Egger,Hans Kirschner,Tim Naumann,Simon Werner,Tobias Vollgraff,Jörg Sundermeyer,Lukas Eschmann,Xiaosheng Yang,Xiaosheng Yang,Dominik Brandstetter,François C. Bocquet,Georg Koller,Alexander Gottwald,Mathias Richter,Michael G. Ramsey,Michael Rohlfing,Peter Puschnig,Michael Gottfried,Serguei Soubatch,F. Stefan Tautz,F. Stefan Tautz +24 more
TL;DR: It is concluded that the π-conjugation of kekulene is better described by the Clar model rather than a superaromatic model, and its electronic structure as determined by angle-resolved photoemission spectroscopy is determined.

Ion-Selective Assembly of Supertetrahedral Selenido Germanate Clusters for Alkali Metal Ion Capture and Separation
TL;DR: In this paper , the supertetrahedral chalcogenido (semi-metalate) cluster-based frameworks possess high selectivity for alkali metal cations matching the specific charge density of their inner surfaces, which enables their use as ion exchange materials.

Anja Haags,Alexander Reichmann,Zilin Ruan,Qitang Fan,Larissa Egger,Hans Kirschner,Tim Naumann,Simon Werner,Olaf A. Kleykamp,Jose Martinez Castro,Felix Lüpke,François C. Bocquet,Christian Kumpf,Serguei Soubatch,Alexander Gottwald,Georg Koller,Michael G. Ramsey,Mathias Richter,Jörg Sundermeyer,Peter Puschnig,J. M. Gottfried,F. S. Tautz,Sabine Wenzel +22 more
TL;DR: Researchers use CO-functionalized STM tips to investigate charge transfer in nonplanar cycloarenes, revealing direct evidence of multi-orbital charge transfer from Cu(111) and Cu(110) surfaces into formerly unoccupied molecular orbitals.
Highly Structure-Selective On-Surface Synthesis of Isokekulene versus Kekulene.
Zilin Ruan,Qitang Fan,Alexander Reichmann,Faming Kang,Tim Naumann,Simon Werner,Olaf A. Kleykamp,Jose Martinez-Castro,Felix Lüpke,Anja Haags,François C. Bocquet,Christian Kumpf,Serguei Soubatch,Jörg Sundermeyer,Peter Puschnig,F. S. Tautz,J. M. Gottfried,Sabine Wenzel +17 more

TL;DR: Researchers demonstrate orthogonal selectivity in on-surface synthesis of isokekulene and kekulene using copper single crystal facets, attributing the difference to distinct adsorption geometries and molecule-substrate interactions, offering an alternative synthesis route for challenging molecules.
Synthesis of Tridecacene by Multistep Single-Molecule Manipulation.
Zilin Ruan,Jakob Schramm,John B Bauer,Tim Naumann,Holger F. Bettinger,R. Tonner-Zech,J. Michael Gottfried +6 more
TL;DR: On-surface synthesis and characterization of tridecacene by single-molecule manipulation reveal a nonmonotonous length-dependent HOMO-LUMO gap and reduced magnetization.
