Restricted Open-Shell Configuration Interaction Singles Study on M- and L-edge X-ray Absorption Spectroscopy of Solid Chemical Systems
Autor: Dimitrios Maganas, Joshua Vura-Weis, Adam Kubas, Max Verkamp, Frank Neese
Publikováno v: Journal of Chemical Theory and Computation. 14:4320-4334
In this study the M- and L-edge X-ray absorption spectra of a series of open- and closed-shell solids (TiO2 rutile, α-Fe2O3 hematite, FeS2 pyrite, and the spinel Co3O4) are investigated with the restricted open-shell configuration interaction single

Carrier- and Element-Specific Femtosecond XUV Transient Absorption of Hybrid Lead Halide Perovskites
Autor: Kaili Zhang, Elizabeth Ryland, Ming-Fu Lin, Andre Schleife, Joshua Vura-Weis, Kristin Benke, Max Verkamp, Joshua Leveillee
Publikováno v: Frontiers in Optics 2017.
Extreme ultraviolet transient absorption spectroscopy is used to measure carrier dynamics in hybrid lead halide perovskites such as CH3NH3PbI3. Distinct signals are observed for photoinduced electrons and holes, allowing the dynamics of each carrier

Charge Carrier Dynamics of Photoexcited Co3O4 in Methanol: Extending High Harmonic Transient Absorption Spectroscopy to Liquid Environments
Autor: Mary K. Gilles, Chang-Ming Jiang, Joshua Vura-Weis, Stephen R. Leone, J. Matthew Lucas, A. Paul Alivisatos, L. Robert Baker, Stephen T. Kelly
Publikováno v: Nano Letters. 14:5883-5890
Charge carrier dynamics in Co3O4 thin films are observed using high harmonic generation transient absorption spectroscopy at the Co M2,3 edge. Results reveal that photoexcited Co3O4 decays to the ground state in 600 ± 40 ps in liquid methanol compar

Dynamics and Efficiency of Hole Transport in LNA:DNA Hybrid Diblock Oligomers
Autor: Arun K. Thazhathveetil, A. Trifonov, Michael R. Wasielewski, Joshua Vura-Weis, Frederick D. Lewis
Publikováno v: Journal of the American Chemical Society. 134:16434-16440
We report here the effect of replacing one or both of the purine or pyrimidine blocks of a diblock stilbene donor-acceptor capped hairpin with locked nucleic acid (LNA) bases on the dynamics and efficiency of hole transport. The structures of the DNA

Crossover from Single-Step Tunneling to Multistep Hopping for Molecular Triplet Energy Transfer
Autor: Joshua Vura-Weis, Michael R. Wasielewski, Sameh H. Abdelwahed, Ruchi Shukla, Mark A. Ratner, Rajendra Rathore
Publikováno v: Science. 328:1547-1550
Tracking Triplet-State Transfers In devices such as organic transistors and photovoltaic cells, energy flow from donor to acceptor sites can occur via electrons that have been excited into higher electronic levels, which create a triplet state with t

Photoinitiated Charge Transport through π-Stacked Electron Conduits in Supramolecular Ordered Assemblies of Donor−Acceptor Triads
Autor: Raanan Carmieli, Joseph E. Bullock, Sarah M. Mickley, Joshua Vura-Weis, Michael R. Wasielewski
Publikováno v: Journal of the American Chemical Society. 131:11919-11929
Photochemical electron donor-acceptor triads having an aminopyrene primary donor (APy) and a p-diaminobenzene secondary donor (DAB) attached to either one or both imide nitrogen atoms of a perylene-3,4:9,10-bis(dicarboximide) (PDI) electron acceptor

Efficient Charge Transport in DNA Diblock Oligomers
Autor: Arun K. Thazhathveetil, Frederick D. Lewis, Joshua Vura-Weis, Michael R. Wasielewski
Publikováno v: Journal of the American Chemical Society. 131:9722-9727
The realization of highly efficient photoinduced charge separation across the pi-stacked base pairs in duplex DNA remains elusive. The low efficiencies (5%) typically observed for charge separation over a dozen or more base pairs are a consequence of

Faster Interprotein Electron Transfer in a [Myoglobin, b5] Complex with a Redesigned Interface
Autor: Jenny V. Lockard, Judith M. Nocek, Peng Xiong, Brian M. Hoffman, Michael R. Wasielewski, Joshua Vura-Weis
Speeding Electron Transfer Between Proteins Compared to those observed in photosynthetic proteins, electron transfer rates between other large biomolecules, such as myoglobin and cytochrome b 5 , are very slow. Xiong et al. (p. 1075 ) show that modif
