Computational study of photoexcited dynamics in bichromophoric cross-shaped oligofluorene
TL;DR: Numerical simulations analyze the effects of molecular geometry distortion during the electronic energy redistribution and suggest spectroscopic signatures reflecting complex electron-vibrational dynamics in a spiro-linked conjugated polyfluorene at room and low temperatures.

Photoinduced dynamics in cycloparaphenylenes: planarization, electron–phonon coupling, localization and intra-ring migration of the electronic excitation
TL;DR: Overall this analysis provides a detailed description of photo excited dynamics in molecular systems with circular geometry, outlines size-dependent trends and connotes specific spectroscopic signatures appearing in time-resolved experimental probes.

Modeling of internal conversion in photoexcited conjugated molecular donors used in organic photovoltaics
TL;DR: In this article, the authors investigate the ultrafast electronic relaxation in a recently synthesized small molecule donor, p-DTS(PTTh2)2, which belongs to the dithienosilole-pyridylthiadiazole family of chromophores.

Energy transfer and spatial scrambling of an exciton in a conjugated dendrimer.
D. Ondarse-Alvarez,N. Oldani,Adrian E. Roitberg,Valeria D. Kleiman,Sergei Tretiak,Sebastian Fernandez-Alberti +5 more
TL;DR: This work investigates the photoinduced processes that take place on a phenylene-ethynylene dendrimer, consisting of nine equivalent linear chromophore units or branches, and finds triple bond excitations coincide with the localization of the electronic transition densities, suggesting that the intramolecular energy redistribution is a concerted electronic and vibrational energy transfer process.

Modification of Optical Properties and Excited-State Dynamics by Linearizing Cyclic Paraphenylene Chromophores
Beatriz Rodriguez-Hernandez,D. Ondarse-Alvarez,N. Oldani,A. Martínez-Mesa,Ll. Uranga-Piña,Sergei Tretiak,Sebastian Fernandez-Alberti +6 more
TL;DR: Cyclic and bent conjugated molecular systems have tunable optical, structural, and dynamical features that differentiate them from their linear counterparts as mentioned in this paper, and they can be classified into two classes: linear and cyclic systems.
