Solitons in polyacetylene
TL;DR: In this paper, a review of the chemical and physical properties of real polyacetylene is given and experimental results on electrical conductivity, magnetic behaviour, optical spectroscopy and photoconductivity are discussed in the context of soliton-like excitations.
Journal ArticleDOI
Photo-excitation in conjugated polymers
TL;DR: In this paper, the authors present polarisation-dependent measurements of photoluminescence (PL) and photo-induced absorption (PA) on highly oriented films of polyacetylene and poly(phenylenevinylene) and identify both monomolecular and bimolecular kinetics for these processes.
Journal ArticleDOI
Shallow and deep traps in conjugated polymers of high intrachain order.
TL;DR: It is shown that charges trapped at depths of 0.1 and 0.4 eV govern the observed charge transport and change in the absorption upon photoexcitation and in particular that the temperature dependence of the PIA intensity in the millisecond range reflects thermal effects on transport processes.

Photogeneration of polaron pairs in conducting polymers.
Esther M. Conwell,H. A. Mizes +1 more
TL;DR: It is shown that photogenerated positive and negative polarons in poly(p-phenylene vinylene), polythiophene, and polyacetylene are, for the most part, bound in pairs by their Coulomb attraction.

An Overview of the Theory of π-Conjugated Polymers
TL;DR: In this article, a review of recent advances in the theoretical modeling of π-conjugated polymers is presented, with an emphasis on quasi-one-dimensional πelectron models that include both electron-phonon and electron-electron interactions.

Soliton excitations in polyacetylene
TL;DR: A theoretical analysis of the excitation spectrum of long-chain polyenes is presented in this paper, where one electronic state is localized at the gap center for each soliton or antisoliton present and the soliton's energy of formation, length, mass, activation energy for motion, and electronic properties are calculated.

Photoexcitations in trans-(CH)x: a Fourier-transform infrared study
TL;DR: In this article, the photoexcitations result in charged solitons which are pinned and the isotope shifts observed in trans-${(\mathrm{CD})}_{x}$ provide new information about the internal modes of the excitation.
