Abstract
As technologies for use in imaging and energy harvesting improve, such devices have delved further and further into the Near-Infrared (NIR) and Short-Wave Infrared (SWIR) regions of the electromagnetic spectrum. Specifically, the NIR (700-1000 nm) and SWIR (1000-1700 nm) regions have gained popularity in the fields of biological and forensic imaging as well as dye-sensitized solar cells. The challenges associated with this region, however, are vast and difficult to overcome. In order to more accurately study new technologies in this region, fundamental studies are needed in order to better understand the effect of excited state electronic structure on phenomena such as emission, hydrogen bonding, and electron capture, and additionally provide new references in this region for more accurate sample characterization. The studies detailed herein aim to combat these challenges by utilizing femtosecond transient absorption spectroscopy (fsTAS) alongside various steady-state spectroscopic techniques and excited-state computational chemistry to probe the excited states of various molecules and complexes, as well as their environments, in order to gain a better understanding of such phenomena.
