Davydov Splitting Without a Davydov Pair and Highly Mobile Singlet Excitons in Perylene Red Microcrystals

Chris Rehhagen, Tolibjon Abdurakhmonov, Magnus Frank +2

We investigate the excitonic properties of perylene red microcrystals, whose unit cell contain eight molecules, using both experimental and theoretical methods. Only two of the nom…

Synthesis, Optoelectronic Properties, and Charge Carrier Dynamics of Colloidal Quasi-two-dimensional Cs3Bi2I9 Perovskite Nanosheets

Sushant Ghimire, Chris Rehhagen, Saskia Fiedler +3

Non-toxicity and stability make two-dimensional (2D) bismuth halide perovskites better alternatives to lead-based ones for optoelectronic applications and catalysis. In this work,…

Site-selective and real-time observation of bimolecular electron transfer during photocatalytic water splitting

Alexander Britz, Sergey I. Bokarev, Tadesse A. Assefa +13

Time-resolved X-ray absorption spectroscopy has been utilized to monitor the bimolecular electron transfer in a photocatalytic water splitting system for the first time. This has b…

Hydrogen Bonding in Ionic Liquids Probed by Linear and Nonlinear Vibrational Spectroscopy

C. Roth, S. Chatzipapadopoulos, D. Kerlé +5

Three imidazolium-based ionic liquids of the type [Cnmim][NTf2] with varying alkyl chain lengths (n = 1, 2 and 8) at the 1 position of the imidazolium ring were studied applying IR…

Quantum Dynamics and Spectroscopy of Excitons in Molecular Aggregates

Oliver Kühn, Stefan Lochbrunner

The theoretical description and the properties of Frenkel excitons in non-covalently bonded molecular aggregates are reviewed from a multi-exciton perspective of dissipative quantu…
