On-surface synthesis of antiaromatic and open-shell indeno[2,1-b]fluorene polymers and their lateral fusion into porous ribbons
Marco Di Giovannantonio, Kristjan Eimre, Aliaksandr V. Yakutovich +8
Polycyclic hydrocarbons have received great attention due to their potential role in organic electronics and, for open-shell systems with unpaired electron densities, in spintronic…
Probing optical excitations in chevron-like armchair graphene nanoribbons
Richard Denk, Alberto Lodi-Rizzini, Shudong Wang +15
The bottom-up fabrication graphene nanoribbons (GNRs) has opened new opportunities to specifically control their electronic and optical properties by precisely controlling their at…
On-surface synthesis of graphene nanoribbons with zigzag edge topology
Pascal Ruffieux, Shiyong Wang, Bo Yang +11
Graphene-based nanostructures exhibit a vast range of exciting electronic properties that are absent in extended graphene. For example, quantum confinement in carbon nanotubes and…
Giant edge state splitting at atomically precise zigzag edges
Shiyong Wang, Leopold Talirz, Carlo A. Pignedoli +4
Zigzag edges of graphene nanostructures host localized electronic states that are predicted to be spin-polarized. However, these edge states are highly susceptible to edge roughnes…
Comparing charge transfer tuning effects by chemical substitution and uniaxial pressure in the organic charge transfer complex tetramethoxypyrene-tetracyanoquinodimethane
Milan Rudloff, Kai Ackermann, Michael Huth +9
In the search for novel organic charge transfer salts with variable charge transfer degree we study the effects of two modifications to the recently synthesized donor-acceptor Tetr…
First-principles modeling of the polycyclic aromatic hydrocarbons reduction
D. W. Boukhvalov, X. Feng, K. Müllen
Density functional theory modelling of the reduction of realistic nanographene molecules (C42H18, C48H18 and C60H24) by molecular hydrogen evidences for the presence of limits in t…
