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) …
