TL;DR: In this article, the structure and stability of quaterthiophene radical cations were studied using density functional calculations, and it was shown that embedding a dimer in a dielectric medium results in stabilizing the dimer, as observed experimentally.

Abstract: A dependence of phonon interaction on the interelectronic distance is found for a translation-invariant (TI) strong-coupling bipolaron. It is shown that the charge induced by the electrons in a TI-bipolaron state is always greater than that in a bipolaron with spontaneously broken symmetry.

TL;DR: In this article, the relationship between electrical properties and type of carrier, polarons and/or bipolarons, in unannealed and annealed PBTTT-C16 in an ionic-liquid-gated transistor (ILGT) configuration using Raman spectroscopy and electrochemical measurements was studied.

TL;DR: In this paper, the effects of the polymer properties on the electronic structure were modeled using the self-consistent reaction field theory in the multicavity approximation (MCa SCRF), and the electronic properties of the respective polymers were extrapolated from the oligomer data.
Abstract: Four common five-membered heterocycles-pyrrole, phosphole, thiophene, and furan- and their oligomers with the chain length of 2, 4, 6, and 10 units have been studied quantum chemically using the semiempirical PM3 parameterization. The oligomers of pyrrole and phosphole with the homolytically dissociated N-H bond and P-H bond, respectively, and oligomers of thiophene and furan with one electron removed per monomer unit (4n + 2 {pi}-electron bipolaron systems) have also been studied. The electronic properties of the respective polymers were extrapolated from the oligomer data. Bulk polymer effects on the electronic structure were modeled using the self-consistent reaction field theory in the multicavity approximation (MCa SCRF). 48 refs., 3 figs., 6 tabs.
