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

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.

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/

Shape-Selective Synthesis of Pentacene Macrocycles and the Effect of Geometry on Singlet Fission
, 2020 Pentacene’s extraordinary photophysical and electronic properties are highly dependent on intermolecular, through-space interactions. Macrocyclic arrangements of chromophores have been shown to provide a high level of control over these interactions, but
