We propose a local heating method via molecular dynamic simulation to investigate the charge transport efficiency along a polypeptide chain in the gas phase. In the protein charge transfer process, the carbonyl groups next to a Cα-hinge collide with each other. Within a critical contact distance between O–O atoms, charge starts to transfer otherwise the charge being at rest. This is termed a bi...
Correction for 'Biocompatible organic charge transfer complex nanoparticles based on a semi-crystalline cellulose template' by Atsushi Nagai et al., Chem. Commun., 2015, 51, 11868-11871.
Diketopyrrolopyrrole (DPP) containing copolymers have gained a lot of interest in organic optoelectronics with great potential in organic photovoltaics. In this work, DPP based statistical copolymers, with slightly different bandgap energies and a varying fraction of donor-acceptor ratio are investigated using monochromatic photocurrent spectroscopy and Fourier-transform photocurrent spectrosco...
Two different nuclear-medium effects are isolated using a low three-momentum transfer subsample of neutrino-carbon scattering data from the MINERvA neutrino experiment. The observed hadronic energy in charged-current ν_{μ} interactions is combined with muon kinematics to permit separation of the quasielastic and Δ(1232) resonance processes. First, we observe a small cross section at very low en...
Dendrimers have been previously shown to provide significant advantages in both excited-state energy transfer and charge transfer. However, this architecture causes one of the charges to be encapsulated and thus not available for charge separation over long distances. We conceived dendron-rod-coils as scaffolds that could have the architectural advantage of the dendrimers, while still providing...
In chlorophyll biosynthesis protochlorophyllide reductase (POR) catalyzes the light-driven reduction of protochlorophyllide (Pchlide) to chlorophyllide, providing a rare opportunity to trap and characterize catalytic intermediates at low temperatures. Moreover, the presence of a chlorophyll-like molecule allows the use of EPR, electron nuclear double resonance, and Stark spectroscopies, previou...
Photo-induced charge transfer at molecular heterojunctions has gained particular interest due to the development of organic solar cells (OSC) based on blends of electron donating and accepting materials. While charge transfer between donor and acceptor molecules can be described by Marcus theory, additional carrier delocalization and coherent propagation might play the dominant role. Here, we d...
Semilocal and hybrid density functional theory was used to study the charge transfer and the energy-level alignment at a representative interface between an extended metal substrate and an organic adsorbate layer. Upon suppressing electronic coupling between the adsorbate and the substrate by inserting thin, insulating layers of NaCl, the hybrid functional localizes charge. The laterally inhomo...
Ultra violet photoelectron spectroscopy measurements in combination with the Integer Charge Transfer model is used to obtain the energy level alignment diagrams for two common types of bulk heterojunction solar cell devices based on poly(3-hexylthiophene) or poly(2-methoxy-5-(3’,7’-dimethyloctyloxy)-1,4-phenylene vinylene) as the donor polymer and (6,6)phenyl-C61-butric-acid as the acceptor mol...
