The work of this dissertation was aimed at synthesizing new types of nanoparticle-DNA conjugates, investigating their chemical and physical properties, and exploring their biodiagnostic applications. Chapters Two and Three describe the synthesis of new types of nanoparticle-DNA conjugates: (1) silver nanoparticle-DNA conjugates (DNA-Ag NPs) and (2) 2-nm gold nanoparticle-DNA conjugates...
Preventing the build-up of indoor pollutants represents an emerging goal in environmental chemistry. Heterogeneous catalysis provides an attractive method of remediating indoor air pollution, but optimization through rational catalyst design requires a detailed understanding of the catalytic surface and surface-pollutant interactions. In this work, a chemical ionization mass spectrometry (CIMS)...
Two new strategies have been developed to accomplish direct nucleophilic acylation reactions. In the first approach, acylsilanes are added to various electrophiles using N-heterocyclic carbenes as catalysts. The second method utilizes O-silyl thiazolium carbinols as stoichiometric acyl anion precursors to afford acylated products under mild reaction conditions.
N-heterocyclic carbenes generated...
The early transition metal oxide fluoride molecular anions with the general formula [MOxF6-x]n- with x = 1 for M = V5+, Nb5+, Ta5+ (n = 2) and x = 2 for M = Mo6+, W6+ (n = 2) feature distorted octahedral coordinations, that arise from electronic dπ pπ metal oxide...
N-Heterocyclic carbene catalysis has recently emerged as an important field in organic chemistry. Two new strategies have been developed to advance the use of N-heterocyclic carbenes (NHCs) as Lewis-base organic catalysts. The first approach utilizes NHCs to catalyze the generation of homoenolates and the conjugated Breslow intermediate is added to...
Theoretical investigation of photochemical processes in molecules is a nontrivial task. Ab initio calculations that completely describe such processes are often intractable to perform given today’s hardware. Thus, to gain insight into common areas of interest, such as in transition metal photochemistry and organic photovoltaics, less accurate but more feasible...
The Controlled, Site-Isolated Synthesis of Polyelemental Nanostructures in Polymer Nanoreactors Pengcheng Chen Polyelemental nanoparticles are an attractive class of materials due to their potential applications, which span the fields of catalysis, plasmonics, electronics, magnetics, targeted drug delivery, and bio-imaging. However, conventional synthetic methods for such structures are limited, especially when...
This thesis describes fundamental photophysical studies of quantum dot (QD)-molecule complexes, aimed at discovering strategies for enhancing the efficiency of QD-photocatalyzed and QD-sensitized multi-electron catalytic reactions, for the purpose of solar fuels production. Photosensitization of molecular catalysts that are active for reactions such as the reduction of carbon dioxide or...
Increasing industrialization and the resulting negative environmental impacts highlight the need to develop alternative renewable energy sources. The Sun is a massive source and organic solar cells are a growing field of study. As new materials are synthesized, the efficiencies of organic solar cells continue to grow, but without an...
