Computational and experimental studies have been performed to investigate the photostability of a series of 6,13-bis(arylalkynyl)-substituted pentacenes in the presence of oxygen. These studies indicate that photostabilization occurs through a selective LUMO orbital stabilization as has been seen previously for 6,13-bis(triisopropylsilylethynyl ...

Toward the peri‐Pentacene Framework
Chemistry – A European Journal, 2013AbstractBased on modern pyrene chemistry, a new route toward the synthesis of the peri‐pentacene framework was developed. Firstly, the tetraketo form as stable precursor was targeted, because the fully aromatic peri‐pentacene is predicted to suffer from high instability and reactivity.

Exploring the Energetic Deposition of Pentacene on Pentacene through Molecular Dynamics Simulations
The Journal of Physical Chemistry C, 2007We use molecular dynamics simulations to explore in detail the factors affecting the behavior of an incident pentacene molecule colliding with the pentacene (010) step edge. We examine the effect of molecular orientation in conjunction with incident kinetic energy (Ei) and angle (θi) of the incoming molecule and proximity of the collision of the ...

9,10,11,20,21,22-Hexaphenyltetrabenzo[a,c,l,n]pentacene (1) was prepared by the reaction of 1,3-diphenylphenanthro[9,10-c]furan with the bisaryne equivalent generated from 1,2,4,5-tetrabromo-3,6-diphenylbenzene in the presence of n-butyllithium, followed by deoxygenation of the double adduct with low-valent titanium.

A water soluble pentacene, potassium 3,3′-(pentacene-6,13-diylbis(sulfanediyl))dipropanoate (4), has been synthesized and characterized. The synthesis of 4 is straightforward and scalable, and its isolation does not require time consuming chromatographic separations.

The effects of ultraviolet (UV) irradiation on the electrical properties of pentacene were investigated in this study. Spectroscopic methods and electrical conductivity measurements were used to characterize the conducting molecule pentacene with and without UV irradiation.

Abstract Energy gap, Mulliken population, and bond-overlap population analyses were carried out to investigate the intermolecular interaction modulation in pentacene clusters by neighboring artificially charged pentacene molecules, which model a charge-carrier injection into a crystal.
