Topological study of the para-line graphs of certain pentacene via topological indices

Open Chemistry, 2018
A topological index is a map from molecular structure to a real number. It is a graph invariant and also used to describe the physio-chemical properties of the molecular structures of certain compounds.

Self-standing chitosan films as dielectrics in organic thin-film transistors

eXPRESS Polymer Letters, 2013
Organic thin film transistors, using self-standing 50 µm thick chitosan films as dielectric, are fabricated using sublimed pentacene or two conjugated polymers deposited by spin coating as semiconductors.

A simple method to prepare self-assembled organic-organic heterobilayers on metal substrates

AIP Advances, 2011
We demonstrate a self-assembly based simple method to prepare organic-organic heterobilayers on a metal substrate. By either sequential- or co-deposition of para-sexiphenyl (p-6P) and pentacene molecules onto the Cu(110) surface in ultrahigh vacuum, p-6P/

On the mechanism of charge transport in pentacene [PDF]

The Journal of Chemical Physics, 2008
Terahertz transient conductivity measurements are performed on pentacene single crystals, which directly demonstrate a strong coupling of charge carriers to low frequency molecular motions with energies centered around 1.1 THz. We present evidence that the strong coupling to low frequency motions is the factor limiting the conductivity in these organic

Influences of electrostatic models on organic crystal structure prediction – a case study of pentacene

, 2022
Crystal structure prediction (CSP) is widely used to explore the molecular packing of organic semiconductors. The reliability of CSP is related to the accurate ranking of trial crystals, which is dependent on the description of the intermolecular ...
