Photoluminescence imaging of solitary dopant sites in covalently doped single-wall carbon nanotubes

TL;DR: A route to control dopant functionalization to a low level as a means for introducing spatially well-separated solitary dopant sites and confirmation of dopants as trapping sites for localization of E(11) excitons following their diffusive transport to the dopant site.
Journal ArticleDOI

Unidirectional Energy Transfer in Conjugated Molecules: The Crucial Role of High-Frequency C≡C Bonds

TL;DR: In this paper, an excited-state nonadiabatic molecular dynamics was used to study energy transfer in dendrimer building blocks, between two-, three-, and four-ring linear polyphenylene ethynylene units linked by meta-substitutions.
Journal ArticleDOI

Electronic Properties of DNA Base Molecules Adsorbed on a Metallic Surface

TL;DR: The internal electronic structure of single deoxyribonucleic acid (DNA) base molecules (i.e., guanine, adenine, cytosine, and thymine) adsorbed on a metallic surface of Cu(111) was determined in detail using density functional theory (DFT) computations as discussed by the authors.
Journal ArticleDOI

Artifacts due to trivial unavoided crossings in the modeling of photoinduced energy transfer dynamics in extended conjugated molecules

TL;DR: In this paper, the transition from interacting/delocalized states to noninteracting/localized states in oligomers of polyphenylene vinylene separated by varying distances is investigated.
Journal ArticleDOI

Excitonic and Vibrational Properties of Single-Walled Semiconducting Carbon Nanotubes**

TL;DR: In this article, the authors review quantum-chemical studies of the excited-state electronic structure of finite-size semiconducting single-walled carbon nanotubes using methodologies previously successfully applied to describe conjugated polymers and other organic molecular materials.
