TLDR
In this article, the decay of an excited singlet exciton into two triplet excitons is suggested to be an important fluorescence quenching channel in crystalline tetracene and its corresponding rate is estimated to be ∼ 4 × 10 10 to 10 12 sec −1.About:

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.

TL;DR: It is pointed out that, in addition to derivatives of large alternant hydrocarbons, those of biradicals are likely candidates for a favorable ordering of excited-state energy levels, E(T2), E(S1) > 2E(T1).

Triplet Excitons in Crystals of Aromatic Molecules
TL;DR: In this article, the Davydov splitting of the first triplet excitons in crystalline naphthalene, anthracene, and biphenyl was studied.
Journal ArticleDOI
Triplet—Triplet Annihilation and Delayed Fluorescence in Molecular Aggregates
TL;DR: In this article, the authors studied the triplet-triplet annihilation in pure and mixed organic crystals and showed that triplet excitation migration may proceed from trap to trap on a time scale which is short compared with the long triplet state lifetime but which is long compared with normal fluorescence lifetime.

Charge‐Transfer Exciton States in Aromatic Molecular Crystals
TL;DR: In this paper, the authors considered the consequences of mixing of neutral exciton states (neutral excitation waves or Frenkel excitons) with charge transfer exciton (i.e., ion-pair exciton) states in the oriented gas model of aromatic molecular crystals.
