Triplet pair states in singlet fission

K Miyata, FS Conrad-Burton, FL Geyer… - Chemical reviews, 2019 - ACS Publications
This account aims at providing an understanding of singlet fission, ie, the photophysical
process of a singlet state (S1) splitting into two triplet states (2× T1) in molecular …

Theoretical modeling of singlet fission

D Casanova - Chemical reviews, 2018 - ACS Publications
Singlet fission is a photophysical reaction in which a singlet excited electronic state splits
into two spin-triplet states. Singlet fission was discovered more than 50 years ago, but the …

Singlet fission in a covalently linked cofacial alkynyltetracene dimer

NV Korovina, S Das, Z Nett, X Feng, J Joy… - Journal of the …, 2016 - ACS Publications
Singlet fission is a process in which a singlet exciton converts into two triplet excitons. To
investigate this phenomenon, we synthesized two covalently linked 5-ethynyl-tetracene (ET) …

Charge transfer–mediated singlet fission

N Monahan, XY Zhu - Annual review of physical chemistry, 2015 - annualreviews.org
Singlet fission, the splitting of a singlet exciton into two triplet excitons in molecular materials,
is interesting not only as a model many-electron problem, but also as a process with …

Tuning singlet fission in π-bridge-π chromophores

E Kumarasamy, SN Sanders… - Journal of the …, 2017 - ACS Publications
We have designed a series of pentacene dimers separated by homoconjugated or
nonconjugated bridges that exhibit fast and efficient intramolecular singlet exciton fission …

Dynamics of the triplet-pair state reveals the likely coexistence of coherent and incoherent singlet fission in crystalline hexacene

NR Monahan, D Sun, H Tamura, KW Williams, B Xu… - Nature …, 2017 - nature.com
The absorption of a photon usually creates a singlet exciton (S1) in molecular systems, but
in some cases S1 may split into two triplets (2× T1) in a process called singlet fission. Singlet …

How morphology affects singlet fission in crystalline tetracene

GB Piland, CJ Bardeen - The journal of physical chemistry letters, 2015 - ACS Publications
The dependence of exciton dynamics on the crystalline morphology of tetracene is
investigated using time-resolved photoluminescence. Single crystals exhibit relatively slow …

Molecular insights and concepts to engineer singlet fission energy conversion devices

R Casillas, I Papadopoulos, T Ullrich, D Thiel… - Energy & …, 2020 - pubs.rsc.org
In this Review, we showcase the fundamental processes of intermolecular and
intramolecular singlet fission (SF). Furthermore we prioritize the information, which is …

Triplet separation drives singlet fission after femtosecond correlated triplet pair production in rubrene

I Breen, R Tempelaar, LA Bizimana… - Journal of the …, 2017 - ACS Publications
Singlet fission, a multistep molecular process in which one photon generates two triplet
excitons, holds great technological promise. Here, by applying a combination of transient …

Maximizing singlet fission by intermolecular packing
