Journal ArticleDOI

Bettina S. Basel,Johannes Zirzlmeier,Constantin Hetzer,Brian T. Phelan,Matthew D. Krzyaniak,S. Rajagopala Reddy,Pedro B. Coto,Noah E. Horwitz,Ryan M. Young,Fraser J. White,Frank Hampel,Timothy Clark,Michael Thoss,Rik R. Tykwinski,Michael R. Wasielewski,Dirk M. Guldi +15 more
TL;DR: The use of time-resolved optical and electron paramagnetic resonance spectroscopy is used to probe singlet fission in a pentacene dimer linked by a non-conjugated spacer and a single kinetic model is developed that describes the data over seven temporal orders of magnitude both at room and cryogenic temperatures.
Journal ArticleDOI
Pentacene Dimers as a Critical Tool for the Investigation of Intramolecular Singlet Fission.
TL;DR: This Minireview describes recent advances using pentacene dimers for the investigation of iSF, where the dimeric structure, and in particular the spacer, allows for controlling and tuning the distance, geometric relationship, and electronic coupling between the two pentacenes moieties.
Journal ArticleDOI
Evidence for Charge-Transfer Mediation in the Primary Events of Singlet Fission in a Weakly Coupled Pentacene Dimer
Bettina S. Basel,Johannes Zirzlmeier,Constantin Hetzer,S. Rajagopala Reddy,Brian T. Phelan,Matthew D. Krzyaniak,Michel Volland,Pedro B. Coto,Ryan M. Young,Timothy Clark,Michael Thoss,Rik R. Tykwinski,Michael R. Wasielewski,Dirk M. Guldi +13 more
TL;DR: In this article, the authors used a combination of transient absorption and electron paramagnetic resonance spectroscopies in conjunction with theoretical calculations to probe Singlet fission in a pentacene dimer linked by a non-conjugated, 1,4-diethynylbicyclo[2.2] octane spacer.
Journal ArticleDOI
Varying the Interpentacene Electronic Coupling to Tune Singlet Fission
Ilias Papadopoulos,Johannes Zirzlmeier,Constantin Hetzer,Youn Jue Bae,Matthew D. Krzyaniak,Michael R. Wasielewski,Timothy Clark,Rik R. Tykwinski,Rik R. Tykwinski,Dirk M. Guldi +9 more
TL;DR: Four different spacers are designed and used to connect two pentacenes and to probe the impact of intramolecular forces on the modulation of pentacene-pentacene interactions and on the key steps in singlet fission (SF) by means of transient absorption and electron paramagnetic resonance measurements.
Journal ArticleDOI
Davydov splitting and singlet fission in excitonically coupled pentacene dimers
Bettina S. Basel,Constantin Hetzer,Johannes Zirzlmeier,Dominik Thiel,Rebecca Guldi,Frank Hampel,Axel Kahnt,Timothy Clark,Dirk M. Guldi,Rik R. Tykwinski +9 more
TL;DR: In this article, the design of pentacene dimers featuring a xanthene linker is described, which strictly places two Pentacene chromophores in a rigid arrangement and enforces efficient, intramolecular π-overlap that mimics interactions typically found in condensed state (e.g., solids, films, etc.).
