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…

Exciton Localization in Extended π-electron Systems: Comparison of Linear and Cyclic Structures
Alexander Thiessen, Dominik Würsch, Stefan-S. Jester +6
We employ five π-conjugated model materials of different molecular shape --- oligomers and cyclic structures --- to investigate the extent of exciton self-trapping and torsional mo…
