Nonadiabatic excited-state molecular dynamics: On-the-fly limiting of essential excited states
(Elsevier Science, 2016-12)
The simulation of nonadiabatic dynamics in extended molecular systems involving hundreds of atoms and large densities of states is particularly challenging. Nonadiabatic coupling terms (NACTs) represent a significant ...
Electronic excited state-specific IR spectra for phenylene ethynylene dendrimer building blocks
(American Chemical Society, 2013-11)
Dendrimers are excellent candidates for applications in molecular devices and light harvesting where creating an energy gradient is crucial. Poly(phenylene ethynylene) (PPE) molecules are building blocks for dendrimers ...
Nonadiabatic excited-state molecular dynamics: treatment of electronic Decoherence
(American Institute of Physics, 2013-06)
Within the fewest switches surface hopping (FSSH) formulation, a swarm of independent trajectories is propagated and the equations of motion for the quantum coefficients are evolved coherently along each independent nuclear ...
Unraveling Direct and Indirect Energy Transfer Pathways in a Light-Harvesting Dendrimer
(American Chemical Society, 2020-10-15)
Light-harvesting and intramolecular energy funneling are fundamental processes in natural photosynthesis. A comprehensive knowledge of the main structural, dynamic, and optical properties that regulate the efficiency of ...
An: Ab initio multiple cloning approach for the simulation of photoinduced dynamics in conjugated molecules
(Royal Society of Chemistry, 2018-05)
We present a new implementation of the Ab Initio Multiple Cloning (AIMC) method, which is applied for non-adiabatic excited-state molecular dynamics simulations of photoinduced processes in conjugated molecules. Within our ...
Photostability enhancement in oligo (phenylene vinylene) systems and their application as heterogeneous photocatalysts
(Universidad Nacional de ColombiaBogotá - Ciencias - Doctorado en Ciencias - QuímicaDepartamento de QuímicaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2022-08-25)
The first chapter revises the most relevant aspects of phenylene vinylene (PV) systems applied to photocatalysis. Despite the photochemical applications of these conjugated systems that have been widely described and involve ...
