A Novel Synthetic Route Towards Conjugated Polymers for Photovoltaic Materials via Metallacycle Transfer
DownloadFall 2012
Conjugated polymers are actively studied as photovoltaic materials in bulk heterojunction solar cell devices. Five-membered heterocycles, typically thiophene and its derivatives, are the most common building units in these polymers. However, conjugated polymers containing inorganic elements other...

Application of a Donor-Acceptor Strategy to Intercept Molecular Main Group Element Precursors en Route to Nanodimensional Materials
DownloadFall 2017
The work in this thesis describes the stabilization of reactive and elusive main group entities with the aid of Wittig reagents, transition metal complexes, or N-heterocyclic carbenes (NHCs) as donors. Wittig reagents were employed to stabilize various group 14 element dihydrides (EH2; E = Ge and...

Delving into Group 16 – Increasing the Accessibility and Understanding the Optoelectronic Properties of Tellurophenes
DownloadFall 2020
This Thesis describes the investigation of 5-membered heterocycles that contain the heavy atom tellurium (Te), termed tellurophenes, as light emitting materials or the active (light absorbing) component in organic photovoltaics. A particular focus was placed on developing new routes to synthesize...

Earth-Abundant Transition Metal Hydride Complexes for Dehydrocoupling and Hydrosilylation Catalysis
DownloadFall 2015
The research presented in this thesis details the synthesis of transition metal hydride complexes, with the focus on utilising these complexes for (a) the dehydrocoupling of amine-borane adducts, and (b) the hydrosilylation and hydroboration of unsaturated organic moieties. In both instances,...

Lewis Base Adducts of Borafluorene: En Route to Polymers and the Discovery of New Luminescent Adducts
DownloadFall 2013
A series of novel Lewis base monoadducts of 9-bromo-9-borafluorene (BrBFl•LB, LB = IPr, IPrCH2, PPh3) and the bisadduct [(DMAP)2BFl]Br were prepared and underwent reactivity studies in the pursuit of incorporating a borafluorene unit into a polymeric scaffold for the sensing of nucleophiles in...
