Machine learning photodynamics decode multiple singlet fission channels in pentacene crystal [PDF]
Nature CommunicationsCrystalline pentacene is a model solid-state light-harvesting material because its quantum efficiencies exceed 100% via ultrafast singlet fission. The singlet fission mechanism in pentacene crystals is disputed due to insufficient electronic information ...

Pentacene–Bridge Interactions in an Axially Chiral Binaphthyl Pentacene Dimer
The Journal of Physical Chemistry A, 2021 Molecular chirality can be exploited as a sensitive reporter of the nature of intra- and interchromophore interactions in π-conjugated systems. In this report, we designed an intramolecular singlet fission (iSF)-based pentacene dimer with an axially chiral binaphthyl bridge (2,2'-(2,2'-dimethoxy-[1,1'-binaphthalene]-3,3'-diyl) n-octyl-di-isopropyl ...

Exciton Dynamics in MoS2-Pentacene and WSe2-Pentacene Heterojunctions
ACS Nano, 2022 We measured the exciton dynamics in van der Waals heterojunctions of transition metal dichalcogenides (TMDCs) and organic semiconductors (OSs). TMDCs and OSs are semiconducting materials with rich and highly diverse optical and electronic properties. Their heterostructures, exhibiting van der Waals bonding at their interfaces, can be utilized in the ...

Carrier Dynamics of Efficient Triplet Harvesting in AgBiS2/Pentacene Singlet Fission Solar Cells
Advanced Science, 2023 Singlet fission is a process by which an organic semiconductor is able to generate two triplet excitons from a single photon. If charges from the triplets can be successfully harvested without heavy losses in energy, then this process can enable a single‐

A Large Starphene Comprising Pentacene Branches [PDF]
Angewandte Chemie International Edition, 2021 AbstractStarphenes are attractive compounds due to their characteristic physicochemical properties that are inherited from acenes, making them interesting compounds for organic electronics and optics. However, the instability and low solubility of larger starphene homologs make their synthesis extremely challenging.
