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 ...

Growth of Pentacene-Doped p-Terphenyl Crystals Using SSVBT and Doping Effects in p-Terphenyl Molecular Crystals

Crystals, 2022
High-quality pentacene-doped p-terphenyl bulk crystals were grown by the selective self-seeding vertical Bridgman technique (SSVBT). The lattice structure and crystal properties of the samples of different doping concentrations and their relations with p-

Tuneable Singlet Exciton Fission and Triplet-Triplet Annihilation in an Orthogonal Pentacene Dimer [PDF]

, 2015
Fast and highly efficient intramolecular singlet exciton fission in a pentacene dimer, consisting of two covalently attached, nearly orthogonal pentacene units is reported. Fission to triplet excitons from this ground state geometry occurs within 1 ps in

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 ...

One-Dimensional Polycyclic Aromatic Hydrocarbons Incorporating Multiple Dithiafulvene Units-Novel Multi-Redox and Electrochromic Systems. [PDF]

Angew Chem Int Ed Engl
Planar polycyclic aromatic hydrocarbons (PAHs) incorporating three or four dithiafulvene (DTF) units were synthesized via Horner–Wadsworth–Emmons reactions to create large π‐conjugated redox‐active frameworks. These molecules display strong intermolecular associations and distinct odd–even redox behavior, enabling formation of mixed‐valence and radical‐
