Journal ArticleDOI
Direct targeting of adsorbate vibrations with mode-tracking
Carmen Herrmann,Markus Reiher +1 more
TL;DR: In this article, the normal modes and vibrational frequencies of a thiophenolate anion adsorbed on an Ag(1/1) surface are directly targeted employing the mode-tracking protocol.
Journal ArticleDOI
Increasing Magnetic Coupling through Oxidation of a Ferrocene Bridge
Suranjan Shil,Carmen Herrmann +1 more
TL;DR: This work has calculated the exchange spin coupling of a ferrocene-coupled nitronyl nitroxide diradical in its neutral and oxidized state and finds that the neutral complex is weakly ferromagnetically coupled (in contrast to experimental results on single crystals), whereas the spin centers in the cationic complex are strongly antiferromag netically coupled, resulting in an overall ferrimagnetic arrangement of the spins.
Journal ArticleDOI
High-conductance surface-anchoring of a mechanically flexible platform-based porphyrin complex
Nadine Hauptmann,Lynn Groß,Kristof Buchmann,Katharina Scheil,Christian Schütt,Franziska L Otte,Rainer Herges,Carmen Herrmann,Richard Berndt +8 more
TL;DR: In this paper, the conductances of molecular model junctions comprising a triazatriangulenium platform with or without an ethynyl spacer and an upright Zn-porphyrin are probed with a low-temperature scanning probe microscope.
Journal ArticleDOI
Design Considerations for Oligo(p-phenyleneethynylene) Organic Radicals in Molecular Junctions
TL;DR: Spin polarization in the electron transmission of radicals is important for understanding single-molecule conductance experiments focusing on shot noise, Kondo properties, or magnetoresistance as mentioned in this paper. But spin polarization in electron transmission is not useful for particle physics.
Journal ArticleDOI
Charge delocalization in an organic mixed valent bithiophene is greater than in a structurally analogous biselenophene.
Ann Christin Jahnke,Jonny Proppe,Mariana Spulber,Cornelia G. Palivan,Carmen Herrmann,Oliver S. Wenger +5 more
TL;DR: The findings indicate that charge delocalization across individual selenophenes tends to be less pronounced than across individual thiophenes, and this may have important implications for long-range charge transfer across selenophene oligomers or polymers.
