This account aims at providing an understanding of singlet fission, ie, the photophysical
process of a singlet state (S1) splitting into two triplet states (2× T1) in molecular …

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 …

This Perspective discusses salient features of the spin-flip approach to strong correlation
and describes different methods that sprung from this idea. The spin-flip treatment exploits …

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 …

The singlet fission (SF) process is generally defined as the conversion of one singlet exciton
(S1) into two triplet excitons (2· T1), which has the potential to overcome thermalization …

Separation of triplet excitons produced by singlet fission is crucial for efficient application of
singlet fission materials. While earlier works explored the first step of singlet fission, the …

Molecular dimers, oligomers, and polymers are versatile components in photophysical and
optoelectronic architectures that could impact a variety of applications. We present a …

Singlet fission is a process that splits collective excitations, or excitons, into two with unity
efficiency. This exciton splitting process, unique to molecular photophysics, has the potential …

The highly unusual state, 1 (TT), is a coupled, double triplet state that has recently garnered
significant attention. This multiexcitonic state can be formed by a quantum transition from a …

Singlet fission, the conversion of a singlet exciton (S1) to two triplets (2× T1), may increase
the solar energy conversion efficiency beyond the Shockley-Queisser limit. This process is …
