Journal ArticleDOI
Up-Conversion Intersystem Crossing Rates in Organic Emitters for Thermally Activated Delayed Fluorescence: Impact of the Nature of Singlet vs Triplet Excited States
TL;DR: The results indicate that having either similar energies for the local-excitation and charge-transfer triplet states or the right balance between a substantial CT contribution to T1 and somewhat different natures of the S1 and T1 states, paves the way toward UISC enhancement and thus TADF efficiency improvement.
Journal ArticleDOI
Charge transport properties in discotic liquid crystals: a quantum-chemical insight into structure-property relationships.
Vincent Lemaur,Demetrio A. da Silva Filho,Veaceslav Coropceanu,Matthias Lehmann,Yves Geerts,Jorge Piris,Michael G. Debije,Anick M van de Craats,Kittusamy Senthilkumar,Laurens D. A. Siebbeles,J. M. Warman,Jean-Luc Brédas,Jérôme Cornil +12 more
TL;DR: A significant increase in the charge mobility when going from triphenylene to hexaazatrinaphthylene is predicted; this finding has been confirmed by measurements carried out with the pulse-radiolysis time-resolved microwave conductivity technique.
Journal ArticleDOI
The Vibrational Reorganization Energy in Pentacene: Molecular Influences on Charge Transport
Nadine E. Gruhn,Demetrio A. da Silva Filho,Tonja G. Bill,M. Malagoli,Veaceslav Coropceanu,and Antoine Kahn,Jean-Luc Brédas +6 more
TL;DR: The reorganization energy upon positive ionization of pentacenes is determined both experimentally and theoretically to be remarkably low, one key element that allows one to rationalize the extremely high hole mobilities recently measured in pentacene single crystals.
Journal ArticleDOI
Hole- and electron-vibrational couplings in oligoacene crystals: intramolecular contributions.
Veaceslav Coropceanu,M. Malagoli,Demetrio A. da Silva Filho,Nadine E. Gruhn,Tonja G. Bill,Jean-Luc Brédas +5 more
TL;DR: The hole-vibrational coupling is found to be significantly smaller than the electron-vibational coupling in the case of these oligomers; however, both quantities are predicted to converge to the same value when increasing the chain length.
Journal ArticleDOI
Delocalization of exciton and electron wavefunction in non-fullerene acceptor molecules enables efficient organic solar cells

TL;DR: The delocalization of exciton and electron wavefunction due to strong π-π packing of Y6 is the key for the high performance of this state-of-the-art OSC system.
