Picosecond time-resolved antibunching measures nanoscale exciton motion, annihilation, and true number of chromophores
Gordon J. Hedley, Tim Schröder, Florian Steiner +8
The particle-like nature of light becomes evident in the photon statistics of fluorescence of single quantum systems as photon antibunching. In multichromophoric systems, exciton d…
Interchromophoric Interactions Determine the Maximum Brightness Density in DNA Origami Structures
Tim Schröder, Max B. Scheible, Florian Steiner +2
An ideal point light source is as small and as bright as possible. For fluorescent point light sources, homogeneity of the light sources is important as well as that the fluorescen…
Determining the True Optical Gap in a High-Performance Organic Photovoltaic Polymer Using Single-Molecule Spectroscopy
Gordon J. Hedley, Florian Steiner, Jan Vogelsang +1
Low-gap conjugated polymers have enabled an impressive increase in the efficiencies of organic solar cells, primarily due to their red absorption which allows harvesting of that pa…
Role of Triplet-State Shelving in Organic Photovoltaics: Single-Chain Aggregates of Poly(3-hexylthiophene) versus Mesoscopic Multichain Aggregates
Florian Steiner, John M. Lupton, Jan Vogelsang
Triplet excitons have been the focus of considerable attention with regards to the functioning of polymer solar cells, because these species are long-lived and quench subsequently…
Molecular polygons probe the role of intramolecular strain in the photophysics of pi-conjugated chromophores
P. Wilhelm, J. Vogelsang, G. Poluektov +5
Pi-conjugated segments - chromophores - constitute the electronically active units of polymer materials used in organic electronics. To elucidate the effect of bending of these lin…
Interactions between pi-conjugated chromophores in a giant molecular spoked wheel
D. Wuersch, R. May, G. Wiederer +4
We discuss the intriguing photophysics of a giant molecular spoked wheel of pi-conjugated arylenealkynylene chromophores on the single-molecule level. This "molecular mesoscopic" t…
