Charge-transfer crystallites as molecular electrical dopants.

Nature communications

Méndez H, Heimel G, Winkler S, Frisch J, Opitz A, Sauer K, Wegner B, Oehzelt M, Röthel C, Duhm S, Többens D, Koch N, Salzmann I.
PMID: 26440403
Nat Commun. 2015 Oct 06;6:8560. doi: 10.1038/ncomms9560.

Ground-state integer charge transfer is commonly regarded as the basic mechanism of molecular electrical doping in both, conjugated polymers and oligomers. Here, we demonstrate that fundamentally different processes can occur in the two types of organic semiconductors instead. Using...

Intramolecular charge transfer assisted by conformational changes in the excited state of fluorene-dibenzothiophene-S,S-dioxide co-oligomers.

The journal of physical chemistry. B

Dias FB, Pollock S, Hedley G, Pålsson LO, Monkman A, Perepichka II, Perepichka IF, Tavasli M, Bryce MR.

J Phys Chem B. 2006 Oct 05;110(39):19329-39. doi: 10.1021/jp0643653.

The strong solvatochromism observed for two fluorene-dibenzothiophene-S,S-dioxide oligomers in polar solvents has been investigated using steady-state and time-resolved fluorescence techniques. A low-energy absorption band, attributed to a charge-transfer (CT) state, is identified by its red shift with increasing solvent...

Odd-even effects in self-assembled monolayers of omega-(biphenyl-4-yl)alkanethiols: a first-principles study.

Langmuir : the ACS journal of surfaces and colloids

Heimel G, Romaner L, Brédas JL, Zojer E.
PMID: 18072797
Langmuir. 2008 Jan 15;24(2):474-82. doi: 10.1021/la7023814. Epub 2007 Dec 12.

Conjugated molecules with a saturated alkyl linker between a thiol docking group and the pi-conjugated core have been shown to form self-assembled monolayers (SAMs) with a high degree of long-range order and uniformity. Additionally, pronounced odd-even effects have been...

Pulsar NP 0532: properties and systematic polarization of individual strong pulses at 430 MHz.

Nature. 1970 May 09;226(5245):529-31. doi: 10.1038/226529a0.

This paper reports further detailed measurements of strong radio pulses from the pulsar NP 0532 in the Crab nebula, recorded at Arecibo.

Tuning the ionization energy of organic semiconductor films: the role of intramolecular polar bonds.

Journal of the American Chemical Society

Salzmann I, Duhm S, Heimel G, Oehzelt M, Kniprath R, Johnson RL, Rabe JP, Koch N.
PMID: 18771262
J Am Chem Soc. 2008 Oct 01;130(39):12870-1. doi: 10.1021/ja804793a. Epub 2008 Sep 05.

For the prototypical conjugated organic molecules pentacene and perfluoropentacene, we demonstrate that the surface termination of ordered organic thin films with intramolecular polar bonds (e.g., -H versus -F) can be used to tune the ionization energy. The collective electrostatics...

Feature extraction for texture discrimination via random field models with random spatial interaction.

IEEE transactions on image processing : a publication of the IEEE Signal Processing Society

Speis A, Healey G.
PMID: 18285151
IEEE Trans Image Process. 1996;5(4):635-45. doi: 10.1109/83.491339.

In this paper, we attack the problem of distinguishing textured images of real surfaces using small samples. We first analyze experimental data that results from applying ordinary conditional Markov fields. In the face of the disappointing performance of these...

Orientation-dependent ionization energies and interface dipoles in ordered molecular assemblies.

Nature materials

Duhm S, Heimel G, Salzmann I, Glowatzki H, Johnson RL, Vollmer A, Rabe JP, Koch N.
PMID: 18264103
Nat Mater. 2008 Apr;7(4):326-32. doi: 10.1038/nmat2119. Epub 2008 Feb 10.

Although an isolated individual molecule clearly has only one ionization potential, multiple values are found for molecules in ordered assemblies. Photoelectron spectroscopy of archetypical pi-conjugated organic compounds on metal substrates combined with first-principles calculations and electrostatic modelling reveal the...

On the rotational temperature and structure dependence of electric field deflection experiments: a case study of germanium clusters.

PMID: 21786999
J Chem Phys. 2011 Jul 21;135(3):034303. doi: 10.1063/1.3610390.

Molecular beam electric field deflection experiments offer a probe to the structural and dielectric properties of isolated particles in the gas phase. However, their quantitative interpretation is still a formidable task. Despite the benefits of this method, the analysis...
