Computational Investigations about the Ground and Excited States’ Properties of Trans-4-N,N-Dimethylamino-4’-Nitro-Stilbene (DNS) and Trans-4-N,N-Dimethyl-Amino-4’-Cyanostilbene (DCS) Derivatives
During the past several years, the field of electro optical organic and nonlinear optical material has received extensive attention [1-3] because of their possible application as fluorescence probes, electro optical switches and chemical sensors. Due to the electron donating and accepting groups on opposite sides, such material, which is connected by a highly delocalized electron system, is imp...
متن کاملMultiple-state interfacial electron injection competes with excited state relaxation and de-excitation to determine external quantum efficiencies of organic dye-sensitized solar cells.
A comprehensive description of the complicated dynamics of excited state evolution and charge transfer at the photochemical interface in dye-sensitized solar cells is crucial to understand the mechanism of converting solar photons to clean electricity, providing an informative basis for the future development of advanced organic materials. By selecting two triarylamine-based organic donor-accep...
متن کاملUltrafast charge transfer in solid-state films of pristine cyanine borate and blends with fullerene
Photoinduced electron transfer in light-absorbing materials is the first step towards charge separation and extraction in small molecule-based organic solar cells. The excited state dynamics of the cyanine dye cation Cy3 paired with a tetraphenylborate counter-anion (Cy3-B) was studied in pristine solid-state films of the dye and in blends with the electron acceptor material PCBM. Here we show ...
متن کاملRole of coherence and delocalization in photo-induced electron transfer at organic interfaces
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...
متن کاملElectron-phonon interactions in MoS2 probed with ultrafast two-dimensional visible/far-infrared spectroscopy.
An ultrafast two-dimensional visible/far-IR spectroscopy based on the IR/THz air biased coherent detection method and scanning the excitation frequencies is developed. The method allows the responses in the far-IR region caused by various electronic excitations in molecular or material systems to be observed in real time. Using the technique, the relaxation dynamics of the photo-excited carrier...
