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…
Differentiation between shallow and deep charge trap states on single poly(3-hexylthiophene) chains through fluorescence photon statistics
Kristin S. Grussmayer, Florian Steiner, John M. Lupton +2
Blinking of the photoluminescence (PL) emitted from individual conjugated polymer chains is one of the central observations made by single-molecule spectroscopy (SMS). Important in…
Mesoscopic Quantum Emitters from Deterministic Aggregates of Conjugated Polymers
Thomas Stangl, Philipp Wilhelm, Klaas Remmerssen +3
An appealing definition of the term "molecule" arises from consideration of the nature of fluorescence, with discrete molecular entities emitting a stream of single photons. We add…
Molecular Water Lilies: Orienting Single Molecules in a Polymer Film by Solvent Vapor Annealing
Dominik Wuersch, Felix J. Hofmann, Theresa Eder +5
The microscopic orientation and position of photoactive molecules is crucial to the operation of optoelectronic devices such as OLEDs and solar cells. Here, we introduce a shape-pe…
Impact of charge carrier injection on single-chain photophysics of conjugated polymers
Felix J. Hofmann, Jan Vogelsang, John M. Lupton
Charges in conjugated polymer materials have a strong impact on the photophysics and their interaction with the primary excited state species has to be taken into account in unders…
