TL;DR: By mapping nuclear motions using femtosecond x-ray pulses, this work has created real-space representations of the evolving dynamics during a well-known chemical reaction and shown a series of time-sorted structural snapshots produced by ultrafast time-resolved hard x-rays.
Journal ArticleDOI

TL;DR: Two regioisomers of bis(10H-phenothiazin-10-yl)dibenzo[b,d]thiophene-S,S-dioxide, a donor–acceptor–donor thermally-activated delayed fluorescence (TADF) emitter, are studied and it is found that donors or acceptors with more than one conformer have negative repercussions for TADF in organic light-emitting diodes.
Journal ArticleDOI
The role of solid state solvation on the charge transfer state of a thermally activated delayed fluorescence emitter
TL;DR: In this paper, the authors used quantum chemistry and molecular dynamics to demonstrate that the magnitude of static solid state solvation effects in a molecular excited state depends not only upon the dipole moment of the host, but also its rigidity and the dipoles of the emitter in its electronic ground state.
Journal ArticleDOI
The contributions of molecular vibrations and higher triplet levels to the intersystem crossing mechanism in metal-free organic emitters

TL;DR: In this paper, the authors demonstrate that the small energy gap between the triplet levels, T1-Tn, below the lowest singlet state, S1, in the angular regioisomers, enhances the coupling between S1 and T1 states and favors ISC and reverse ISC (rISC).
Journal ArticleDOI

TL;DR: It is demonstrated that sensitivity to individual wavepacket components can be modulated by the probe energy and that the bond length change associated with molecular breathing mode can be tracked with a sub-Angstrom resolution beyond optical-domain observables.
