Abstract:

This work focusses on seeking to gain a deep understanding of the photophysical processes inherent to multi-functional and/or multi-component supermolecules in the condensed phase. To do this, a variety of molecular systems have been subjected to spectroscopic examination, most commonly using steady-state and time-resolved emission spectroscopy to interrogate the samples. A common feature of all the molecular architectures examined herein relates to the possibility for structural motion on timescales of concern to the photophysical event. Furthermore, to provide a spectroscopic signature, most

Thesis advisor: Torsten Fiebig<br>Thesis advisor: Mary Roberts<br>Understanding the electronic nature of DNA is profound and has been attempted for decades. Photoexcitation of DNA with UV light deposits electronic energy in the base stack and prepares highly reactive excited states. These states are precursors for photoinduced damage reactions which can lead to mutations and ultimately to cell death. While many DNA photo products have been isolated and characterized, the primary events immediately after photon absorption are not yet understood. Recent studies with ultrafast lasers have reveale

Abstract:

Chromophore is a molecule or a part of a molecule which is responsible for its appearance color. This definition has been evolving over time with the progress of science. Contemporary scientific advances have expanded its meaning: to an inclusive level, chromophore is an irreducible collective of fundamental particles, which can represent the photophysical (optical physical) properties of the macroscopic matter. Previous studies have already found that the same molecule can have different photophysical properties under different condensed states. Therefore, it is straight forward to conclude t

Abstract:

This thesis is concerned with measuring ultrafast electron dynamics taking place in dye-sensitized mesoporous semiconductor films employed as working electrodes in dye-sensitized solar cells (DSCs). An understanding of these ultrafast charge transfer mechanisms is essential for designing efficient photovoltaic (PV) devices with high photon-to-current conversion efficiency. Optical-pump terahertz-probe (OPTP) spectroscopy is a sub-picosecond resolution, non-contact, photoconductivity measurement technique which can be used to directly measure charge carrier dynamics within nanostructured materi

These points are not isolated points, CI form seam between PES. One way to study they is to find the minimum energy CI (MECI). For this reason, in this thesis, a new algorithm for finding MECI has been proposed: Double Newton-Raphson (DNR).
