Exciton Dynamics in MoS₂-Pentacene and WSe₂-Pentacene Heterojunctions [PDF]

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 ...

Aryl substitution of pentacenes [PDF]

Beilstein Journal of Organic Chemistry, 2014
A series of 11 new pentacene derivatives has been synthesized, with unsymmetrical substitution based on a trialkylsilylethynyl group at the 6-position and various aryl groups appended to the 13-position.

Pentacene‐Fused Diporphyrins

Chemistry – A European Journal, 2014
AbstractIn this work, we report the synthesis, spectroscopic characterization, and theoretical analysis of a linearly conjugated pentacene‐fused porphyrin dimer and cross‐conjugated quinone‐fused dinaphtho[2,3]porphyrins. These multichromophoric systems display non‐typical UV‐visible absorptions of either porphyrins or pentacenes/quinones.

Machine learning photodynamics decode multiple singlet fission channels in pentacene crystal [PDF]

Nature Communications
Crystalline 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 ...

Modeling the Polymorphism of Pentacene [PDF]

Journal of the American Chemical Society, 2003
Thin films of pentacene are known to crystallize in at least four different polymorphs. All polymorphs are layered structures that are characterized by their interlayer spacing d(001). We develop a model that rationalizes the size of the interlayer spacing in terms of intralayer shifts of the pentacene molecules along their long molecular axes.

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‐
