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 (SF) is a photophysical downconversion pathway, in which a singlet excitation
transforms into two triplet excited states. As such, it constitutes an exciton multiplication …

Singlet exciton fission is a carrier multiplication process in organic semiconductors that
generates two electron–hole pairs for each photon absorbed. Singlet fission occurs on sub …

From biological complexes to devices based on organic semiconductors, spin interactions
play a key role in the function of molecular systems. For instance, triplet-pair reactions …

Multiexciton quintet states, 5 (TT), photogenerated in organic semiconductors using singlet
