Journal ArticleDOI
Singlet exciton fission in solution
TL;DR: A triplet yield of 200% and triplet formation rates approaching the diffusion limit in solutions of bis(triisopropylsilylethynyl (TIPS) pentacene are reported, and a transient bound excimer intermediate is observed, formed by the collision of one photoexcited and one ground-state TIPS-pentacene molecule.
Journal ArticleDOI
Evidence for conical intersection dynamics mediating ultrafast singlet exciton fission
Andrew J. Musser,Matz Liebel,Christoph Schnedermann,Torsten Wende,Tom B. Kehoe,Akshay Rao,Philipp Kukura +6 more
TL;DR: In this article, a vibrational wavepacket generated in a spin singlet is shown to be transferable to spin triplets during singlet fission in organic semiconductors.
Journal ArticleDOI
Vibronically Coherent Ultrafast Triplet-Pair Formation and Subsequent Thermally Activated Dissociation Control Efficient Endothermic Singlet Fission

TL;DR: The triplet pair state (TT), which has been proposed to mediate singlet fission, forms on ultrafast timescales and is mediated by the strong coupling of electronic and vibrational degrees of freedom, which provides a model for 'temperature-independent' efficient TT formation and thermally activated TT separation.
Journal ArticleDOI
Tuneable Singlet Exciton Fission and Triplet-Triplet Annihilation in an Orthogonal Pentacene Dimer
Steven Lukman,Andrew J. Musser,Kai Chen,Stavros Athanasopoulos,Chaw K. Yong,Zebing Zeng,Qun Ye,Chunyan Chi,Justin M. Hodgkiss,Jishan Wu,Richard H. Friend,Neil C. Greenham +11 more
TL;DR: In this article, fast and highly efficient intramolecular singlet exciton fission in a pentacene dimer, consisting of two covalently attached, nearly orthogonal units, was reported.
Journal ArticleDOI

TL;DR: This work uses a range of organic semiconductors that undergo singlet exciton fission to reveal the photophysical properties of entangled triplet-pair states and finds that the triplet pair is bound with respect to free triplets with an energy that is largely material independent (∼30 meV).
