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.

Stabilization of Acenes: “Geländer”‐Pentacenes

Angewandte Chemie International Edition
AbstractWe report soluble tetrakis‐biphenylyl substituted pentacenes comprised of sp2 carbons and synthesized from pentacene‐5,7,12,14‐tetraone. Intramolecular Yamamoto coupling of two tetrakis(chlorobiphenylyl)pentacenes yields helical, doubly wrapped pentacenes, in which the quaterphenylene units solubilize the pentacenes and shield their central ...

Pentacene on Ni(111): Room-temperature molecular packing and temperature-activated conversion to graphene

, 2015
We investigate, using scanning tunnelling microscopy, the adsorption of pentacene on Ni(111) at room temperature and the behaviour of these monolayer films with annealing up to 700 °C.

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 ...

Oberflächencharakterisierung auf atomarer Ebene: Vom Sehen einzelner Atome zum Verständnis chemischer Prozesse

Physik in unserer Zeit, EarlyView.
Sehen ist der erste Schritt in Richtung Verstehen. Dieses Prinzip gilt von der Beobachtung ferner Galaxien bis hin zur Untersuchung einzelner Atome und hält damit über viele Größenordnungen. Heutzutage ermöglichen moderne Mikroskope die Beobachtung einzelner Atome und sogar die gezielte Kontrolle chemischer Reaktionen einzelner Moleküle ...

Organic semiconductors for organic field-effect transistors

Science and Technology of Advanced Materials, 2009
The advantages of organic field-effect transistors (OFETs), such as low cost, flexibility and large-area fabrication, have recently attracted much attention due to their electronic applications.

40 years of measuring properties with atomic force microscopy

Journal of Microscopy, EarlyView.
Abstract This paper gives a short personal retrospective of some of the AFM methods developed in the Grutter group. It gives an overview of methods developed with the aim of measuring properties with high spatial and temporal resolution. Frequency mode AFM has over the past 40 years developed into a spatially resolving technique allowing spectroscopy ...

Ultrafast carrier dynamics in pentacene, functionalized pentacene, tetracene, and rubrene single crystals [PDF]

, 2006
We measure the transient photoconductivity in pentacene, functionalized pentacene, tetracene, and rubrene single crystals using optical pump-terahertz probe techniques.
