Fluctuating exciton localisation in giant pi-conjugated spoked-wheel macrocycles
Vikas Aggarwal, Alexander Thiessen, Alissa Idelson +8
Conjugated polymers offer potential for many diverse applications but we still lack a fundamental microscopic understanding of their electronic structure. Elementary photoexcitatio…

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…
