Solar energy is an ample renewable energy resource, with photovoltaic (PV) technology
enabling a direct route from light to electricity. Currently, PVs are limited in photon …

The quintet triplet-pair state may be generated upon singlet fission and is a critical
intermediate that dictates the fate of excitons, which can be exploited for photovoltaics …

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 …

Developing highly efficient heavy-metal-free photosensitizers (PSs) for the production of
reactive oxygen species (ROS) is urgent to achieve wide applications of ROS, yet it remains …

Singlet fission and triplet-triplet annihilation upconversion are two multiexciton processes
intimately related to the dynamic interaction between one high-lying energy singlet and two …

Singlet fission (SF), a process that involves the conversion of one singlet exciton (S1) into a
pair of triplet excitons (T1), holds great technological promise for photovoltaics. Typical SF …

We newly synthesized a series of homo‐and hetero‐tetracene (Tc) oligomers to propose a
molecular design strategy for the efficient exciton transport in linear oligomers by promoting …

Singlet fission is commonly defined as the generation of two triplet excitons from a single
absorbed photon. However, ambiguities within this definition arise due to the complexity of …

Singlet fission (SF) has drawn tremendous attention as a multiexciton generation process
that could mitigate the thermal loss and boost the efficiency of solar energy conversion …

Triplet dynamics in singlet fission depend strongly on the strength of the electronic coupling.
Covalent systems in solution offer precise control over such couplings. Nonetheless, efficient …
