Journal ArticleDOI
Hot charge-transfer excitons set the time limit for charge separation at donor/acceptor interfaces in organic photovoltaics
Askat E. Jailaubekov,Adam P. Willard,John R. Tritsch,Wai-Lun Chan,Na Sai,Raluca I. Gearba,Loren G. Kaake,Loren G. Kaake,Kenrick J. Williams,Kevin Leung,Peter J. Rossky,Xiaoyang Zhu,Xiaoyang Zhu +12 more
TL;DR: This real-time view of hot CT exciton formation and relaxation using femtosecond nonlinear optical spectroscopies and non-adiabatic mixed quantum mechanics/molecular mechanics simulations in the phthalocyanine-fullerene model OPV system sets the fundamental time limit for competitive charge separation channels that lead to efficient photocurrent generation.
Journal ArticleDOI
Observing the multiexciton state in singlet fission and ensuing ultrafast multielectron transfer.

TL;DR: Using the model system of pentacene/fullerene bilayers and femtosecond nonlinear spectroscopies, the state ensuing from singlet fission is observed and it is found that multiple electron transfer from the ME state to the fullerene occurs on a subpicosecond time scale, which is one order of magnitude faster than that from the triplet exciton state.
Journal ArticleDOI
Excitation-energy dependence of the mechanism for two-photon ionization of liquid H2O and D2O from 8.3to12.4eV
TL;DR: Modeling the kinetics of the electron reveals its average ejection length from the hydronium ion and hydroxyl radical counterparts and thus provides insight into the ionization mechanism, which is consistently shorter in liquid water than in H(2)O.
Journal ArticleDOI
Rotational coherence and a sudden breakdown in linear response seen in room-temperature liquids.

TL;DR: Molecular dynamics simulations trace this slow development of molecular-scale friction to an abrupt liquid-structure change triggered by the rapid rotation, showing that molecular relaxation can sometimes switch from linear to nonlinear response.
Journal ArticleDOI
Tunable 30-femtosecond pulses across the deep ultraviolet
TL;DR: In this paper, phase-matched four-wave mixing in an argon-filled hollow waveguide using 100-fs pulses from a commercial Ti:sapphire regenerative amplifier was used to generate femtosecond pulses in the deep ultraviolet.
