A survey is provided of recent progress in the understanding of singlet fission, a spin-
allowed process in which a singlet excited molecule shares its energy with a ground-state …

In the following we provide a comprehensive review of singlet fission in organic materials.
We first sketch an outline of the underlying theory and then turn to molecular crystals …

Singlet fission, in which two triplet excitons are generated from a single absorbed photon, is
a key third-generation solar cell concept. Conservation of angular momentum requires that …

Although the interest in experimental evidence of magnetic field effects (MFEs) on the
kinetics of chem-ical reactions, which might be characterized by the term “magnetokinetics” …

Excimers are dimers with associated excited electronic states, dissociative ground states,
and structureless emission spectra. Noble and other monatomic gases form atomic …

The photophysical behavior of organic semiconductors is governed by their excitonic states.
In this review, I classify the three different exciton types (Frenkel singlet, Frenkel triplet, and …

We compare the singlet fission dynamics of five pentacene derivatives precipitated to form
nanoparticles. Two nanoparticle types were distinguished by differences in their solid-state …

A detailed analysis of the oscillations seen in the delayed fluorescence of crystalline
tetracene is presented in order to study the mechanism of singlet fission. Three quantum …

We discuss possible improvements in the efficiency of dye-sensitized photovoltaic cells
using dyes capable of singlet fission into two triplets, thus producing two electron− hole pairs …

The dependence of exciton dynamics on the crystalline morphology of tetracene is
investigated using time-resolved photoluminescence. Single crystals exhibit relatively slow …
