Singlet exciton fission in organic chromophores has received much attention during the past
decade. Inspired by numerous spectroscopic studies in the solid state, there have been …

Singlet fission (SF), which can convert one singlet exciton into two triplet excitons, has the
potential to enhance the solar energy conversion efficiency in devices such as photovoltaic …

We present an experimental study investigating the solvent-dependent dynamics of a 9, 10-
bis (phenylethynyl) anthracene monomer, dimer, and trimer. Using transient absorption …

Singlet fission in organic chromophores holds the potential for enhancing photovoltaic
efficiencies beyond the single-junction limit. The most basic requirement of a singlet fission …

Lanthanide-doped nanoparticles (LnNPs) possess unique optical properties and are
employed in various optoelectronic and bioimaging applications. One fundamental limitation …

In this work, detailed experimental proof and in-depth analysis of the singlet fission (SF)
mechanism, operative in fluorene-based small molecules, are carried out by employing …

A theory of singlet fission (SF) in carotenoid dimers is applied to explain the SF in lycopene
H-aggregates observed after high-energy photoexcitation. The explanation proposed here is …

A key challenge in the search of new materials capable of singlet fission (SF) arises from the
primary energy conservation criterion, ie, the energy of the triplet exciton has to be half that …

Singlet fission (SF) and triplet–triplet annihilation upconversion (TTA-UC) nominally enable
the interconversion of higher-energy singlet states with two lower-energy triplet states and …

In molecular dimers that undergo intramolecular singlet fission (iSF), efficient iSF is typically
accompanied by triplet pair annihilation at rates which prohibit effective triplet harvesting …
