Growth of large-size-two-dimensional crystalline pentacene grains for high performance organic thin film transistors

AIP Advances, 2012
New approach is presented for growth of pentacene crystalline thin film with large grain size. Modification of dielectric surfaces using a monolayer of small molecule results in the formation of pentacene thin films with well ordered large crystalline ...

Singlet fission in pentacene dimers [PDF]

Proceedings of the National Academy of Sciences, 2015
SignificanceIn the present work, we show compelling evidence for the unprecedented intramolecular singlet fission at room temperature and in dilute solutions within a set of three different regioisomeric pentacene dimers. Pump–probe experiments, which were complemented by theoretical calculations using high-level ab initio multireference perturbation ...

Influences of electrostatic models on organic crystal structure prediction – a case study of pentacene

, 2022
Crystal structure prediction (CSP) is widely used to explore the molecular packing of organic semiconductors. The reliability of CSP is related to the accurate ranking of trial crystals, which is dependent on the description of the intermolecular ...

Polarizing agents beyond pentacene for efficient triplet dynamic nuclear polarization in glass matrices

, 2023
Triplet dynamic nuclear polarization (triplet-DNP) is a technique that can obtain high nuclear polarization under moderate conditions. However, in order to obtain practically useful polarization, large single crystals doped with a polarizing agent must ...
