Internal Stark effect of single-molecule fluorescence
Kirill Vasilev, Benjamin Doppagne, Tomáš Neuman +5
The optical properties of chromophores can be efficiently tuned by electrostatic fields generated in their close environment, a phenomenon that plays a central role for the optimiz…
Energy funnelling within multichromophore architectures monitored with subnanometre resolution
Shuiyan Cao, Anna Rosławska, Benjamin Doppagne +6
In natural and artificial light-harvesting complexes (LHC) the resonant energy transfer (RET) between chromophores enables an efficient and directional transport of solar energy be…
Electrofluorochromism at the single molecule level
Benjamin Doppagne, Michael C. Chong, Hervé Bulou +3
The interplay between the oxidation state and the optical properties of molecules plays a key role for applications in displays, sensors or molecular-based memories. The fundamenta…
Imaging isodensity contours of molecular states with STM
Gaël Reecht, Benjamin Heinrich, Hervé Bulou +3
We present an improved way for imaging the local density of states with a scanning tunneling microscope, which consists in mapping the surface topography while keeping the differen…
Electrically-driven vibronic spectroscopy with sub-molecular resolution
Benjamin Doppagne, Michael C. Chong, Etienne Lorchat +6
A scanning tunneling microscope is used to generate the electroluminescence of phthalocyanine molecules deposited on NaCl/Ag(111). Photon spectra reveal an intense emission line at…
Narrow-line single-molecule transducer between electronic circuits and surface plasmons
Michael C. Chong, Gaël Reecht, Hervé Bulou +4
A molecular wire containing an emitting molecular center is controllably suspended between the plasmonic electrodes of a cryogenic scanning tunneling microscope. Passing current th…
Pulling and Stretching a Molecular Wire to Tune its Conductance
Gaël Reecht, Hervé Bulou, Fabrice Scheurer +5
A scanning tunnelling microscope is used to pull a polythiophene wire from a Au(111) surface while measuring the current traversing the junction. Abrupt current increases measured…
Oligothiophene nano-rings as electron resonators for whispering gallery modes
Gaël Reecht, Hervé Bulou, Fabrice Scheurer +4
Structural and electronic properties of oligothiophene nano-wires and rings synthesized on a Au(111) surface are investigated by scanning tunneling microscopy. The spectroscopic da…
