Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials

Laser &Photonics Reviews, EarlyView.
This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...

Machine learning photodynamics decode multiple singlet fission channels in pentacene crystal

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 ...

Molecular-resolution imaging of pentacene on KCl(001)

Beilstein Journal of Nanotechnology, 2012
The growth of pentacene on KCl(001) at submonolayer coverage was studied by dynamic scanning force microscopy. At coverages below one monolayer pentacene was found to arrange in islands with an upright configuration.

Investigation of the Dielectric and Electrical Properties of Poly(chloro‐p‐xylylene) (Parylene‐C) Layers for Controlling Charge Transport in Organic Field‐Effect Transistors

Macromolecular Materials and Engineering, EarlyView.
This study examines the π–π stacking behavior of organic semiconductors on poly(chloro‐p‐xylylene) dielectric layers and elucidates its influence on molecular ordering and charge transport properties. Based on these observations, organic transistors with optimized electrical performance are fabricated, offering valuable insights for the development of ...

Direct Write, Read, and Erase of a Vertical Heterostructure of Graphene–Monolayer Electrolyte–h‐BN Using Electric Force Microscopy

Small, EarlyView.
This work demonstrates bistable graphene doping of about 5 × 1012 cm−2$\rm{c{m}^{-2}}$ using a molecularly thin electrolyte confined between two, 2D crystals. The electrolyte's bistability enables multiple non‐volatile states with a conductive AFM tip writing, erasing, and sensing these states.

Raman Identification of Polymorphs in Pentacene Films

Crystals, 2016
We use Raman spectroscopy to characterize thin films of pentacene grown on Si/SiO x by Supersonic Molecular Beam Deposition (SuMBD). We find that films up to a thickness of about 781 Å (∼ 52 monolayers) all belong to the so-called thin-film (TF ...

Rh‐Catalyzed [2 + 2 + 2] Cycloaddition of Linked Bis(Diynes) Ar‐C≡C‐C≡C‐(CH2)3‐C≡C‐C≡C‐Ar With Quinones: Synthesis and Photophysical Properties of Bis(Arylethynyl)‐Naphthoquinones and Anthraquinones

Chemistry – A European Journal, Volume 32, Issue 11, 16 March 2026.
We report the synthesis bis(arylethynyl)naphtho‐ and anthraquinones via Rh(I)‐catalyzed [2 + 2 + 2] cycloaddition reactions. The substrate scope of both quinones and linked bis‐diynes was explored. Microwave irradiation remarkably enhanced yields.
