On-surface synthesis and aromaticity of large cyclocarbons

Lisanne Sellies, Marco Vitek, Yueze Gao +12

Molecular rings of N carbon atoms, that is, cyclo[N]carbons, or C, can be formed by tip-induced chemistry [1-7]. Because of their monocyclic geometry, cyclocarbons are fundamen…

A molecule with half-Möbius topology

Igor Roncevic, Fabian Paschke, Yueze Gao +10

Stereoisomers of CCl exhibiting helical orbitals around a ring of carbon atoms were synthesized by atom manipulation on NaCl surfaces. We resolved the enantiomeric geome…

Tip-induced nitrene generation

Leonard-Alexander Lieske, Aaron H. Oechsle, Igor Rončević +6

We generated trinitreno-s-heptazine, a small molecule featuring three nitrene centers, by tip-induced chemistry from the precursor 2,5,8-triazido-s-heptazine on bilayer NaCl on Au(…

Bistability between -diradical open-shell and closed-shell states in indeno[1,2-a]fluorene

Shantanu Mishra, Manuel Vilas-Varela, Leonard-Alexander Lieske +7

Indenofluorenes are non-benzenoid conjugated hydrocarbons that have received great interest owing to their unusual electronic structure and potential applications in non-linear opt…

Charge-state lifetimes of single molecules on ultrathin insulating films

Katharina Kaiser, Leonard-Alexander Lieske, Jascha Repp +1

In scanning tunneling microscopy (STM) experiments of molecules on insulating films, tunneling through molecular resonances implies transiently charging the molecule. The transitio…
