Novel primary photoexcitations in -conjugated donor-acceptor copolymers probed by transient magneto-photoinduced-absorption
Uyen N. V. Huynh, Tek P. Basel, L. Dou +6
The saga of the primary photoexcitations in -conjugated polymers has been a source of extraordinary scientific curiosity that has lasted for more than three decades. From solito…
Theory of Primary Photoexcitations in Donor-Acceptor Copolymers
Karan Aryanpour, Tirthankar Dutta, Uyen N. V. Huynh +2
We present a generic theory of primary photoexcitations in low band gap donor-acceptor conjugated copolymers. Because of the combined effects of strong electron correlations and br…
Theory of Singlet Fission in Polyenes, Acene Crystals and Covalently Linked Acene Dimers
Karan Aryanpour, Alok Shukla, Sumit Mazumdar
We report quadruple configuration interaction calculations within the extended PariserParrPople Hamiltonian on the excited states of aggregates of polyenes, crystalline acene…
Subgap Two-Photon States in Polycyclic Aromatic Hydrocarbons: Evidence for Strong Electron Correlations
K. Aryanpour, A. Roberts, A. Sandhu +3
Strong electron correlation effects in the photophysics of quasi-one-dimensional -conjugated organic systems such as polyenes, polyacetylenes, polydiacetylenes, etc., have been…
Electron Correlations and Two-Photon States in Polycyclic Aromatic Hydrocarbon Molecules: A Peculiar Role of Geometry
K. Aryanpour, A. Shukla, S. Mazumdar
We present numerical studies of one- and two-photon excited states ordering in a number of polycyclic aromatic hydrocarbon molecules: coronene, hexa-peri-hexabenzocoronene and circ…
Does Singlet Fission Enhance the Performance of Organic Solar Cells?
K. Aryanpour, J. A. Muñoz, S. Mazumdar
Singlet fission, in which the optical spin-singlet exciton dissociates into two low energy triplet excitons, has been proposed as a viable approach to enhance the quantum efficienc…
