Hydrogenation of nanostructured carbon, synthesis of organic semiconductors and progress towards synthesis of fullerenes and nanoribbons from polyaromatic hydrocarbons
… shown that a two-carbon spacer between amine groups is critical for efficient hydrogenation, as well as the presence of at least two adjacent amines that are not tertiary. The extent of hydrogenation on the fullerenes is a function of reaction temperature. C3nuC 60H18 forms preferentially at …

Electronic characterization of solution-synthesized graphene nanoribbons using scanning tunneling microscopy
This thesis reviews the methods of using bottom-up synthesis to fabricate atomically precise graphene nanoribbons (GNRs). Previous works of on-surface heterojunction GNRs and the dry contact transfer method for solution-synthesized GNRs are presented to show the current status of GNR fabrication. …

Microwave-Assisted Synthesis of Excitation-Dependent Photoluminescent Graphene Nanosheets from Glucose
… (GNS) have attracted attention because of their superior water dispersibility, chemical inertness, photostability against bleaching and low toxicity compared to other carbon materials. In this work, we explored a facile approach to the synthesis of GNS through microwave-assisted carbonization of …

Silicon nanoparticle sysnthesis through thermal catalytic pyrolysis
… such as milling, laser ablation or etching, and bottom-up synthesis such as colloidal chemistry and gas phase pyrolysis. The chemical processes in the latter are generally equivalent to those in the chemical vapour deposition (CVD) of compact films. Due to its simplicity and the relatively …

Enabling Starting Material-Oriented Strategies in Computer-Aided Synthesis Planning With a Bidirectional Search Algorithm
Retrosynthesis, in which one proposes a reaction pathway towards a target molecule from simpler starting materials, is a fundamental task in synthetic chemistry. Current computational search methods assume the sufficiency of reaching arbitrary building blocks but fail to address the common …

The design and synthesis of linear and macrocyclic Poly(para-arylene)s
… in their scope. In Chapter 2 we discuss the synthesis of poly(para-arylene)s via the post polymerization functionalization of a completely soluble and easily accessible precursor polymer, utilizing the metal-catalyzed [2+2+2] reaction. We expect that this versatile strategy could lead to new …

On-demand production of deoxynucleotides from genomic DNA
… countries. This thesis explores a novel synthesis method to produce a key NAAT reagent, namely the 2'-deoxynucleoside 5'-triphosphate (dNTPs) building blocks of DNA, in a manner that can be integrated into a NAAT workflow. A unique top-down approach to produce dNTP monomers from a genomic …
