This thesis document is comprised of three research projects. The first investigates the active vibrational modes involved in twisted intramolecular charge transfer in a Julolidine-BODIPY dyad using two-dimensional electronic spectroscopy along with DFT calculations. We identified two types of vibrations, compression and torsional motion, as playing an important role in...
For many years silicon tethers have been used to increase yields and control the stereochemical and regiochemical outcomes of coupling reactions. Silicon tethers may be incorporated into a wide range of reaction types including alkene metathesis, cycloadditions, and glycosylations. This thesis focuses on the development of the use of silicon...
Photochemistry allows chemists to harness the energy in specific wavelengths of light and use it to achieve new chemical transformations. These chemical transformations are often impossible or energetically demanding under traditional thermal conditions. My dissertation focuses broadly on different strategies to apply visible-light photochemistry and photocatalysis to the development of...
In recent years, motivated by the approaching of quantum limit for classic information science, the development of quantum information science (QIS) has drawn considerable interest from chemists and physicians. Different from classical bits which can only be localized on two different states, quantum bit, which can be simplified as qubit,...
Biologically active small molecules remain the foundation for the medical management of human disease. Their impacts on human health, longevity, culture, and society are difficultly overstated. In large part, medicines derived from organic compounds are the result of the tireless efforts of chemical practitioners––both past and present––who have dedicated much...
Photochemistry is an inherently interdiscplinary field where very large energies are leveraged for the making and breaking of bonds. My work has broadly dealt with various strategies to control how energy delivered by light can be channeled into useful functions. I developed a strategy to control the chemo- and stereo-selectivity...
The construction of new C–C bonds remains a central facet of organic chemistry due to its critical role in the synthesis of pharmaceutical compounds and organic materials. Mild and selective methodologies are often required for efficient formation of these bonds in natural product total synthesis, medicinal chemistry campaigns, and more....
Part I: Evaluating the relationship between Crosslink Kinetics and Thermodynamics with the hydrogel mechanics. The past two decades have witnessed a surge of applications built upon dynamic covalent chemistry (DCC), both attributed to the scope of developed reactions as well as their modularity.1-3 These reactions have comparable strengths to their...
Secondary organic aerosol (SOA) particles are a class of highly abundant atmospheric constituents that represent a substantial fraction of carbon within the climate system. A subset of naturally-occurring SOA particles are formed through atmospheric oxidation of biogenic volatile organic compounds (BVOCs), forming oxygenated products of lower volatility that can partition...
Part I:Current approaches to synthesize π-conjugated polymers are dominated by thermally driven, transition-metal-mediated reactions. Herein we7 show that electron-deficient Grignard monomers readily polymerize under visible-light irradiation at room temperature in the absence of a catalyst. The product distribution can be tuned by the wavelength of irradiation based on the absorption...
