Abstract

This thesis, comprising two parts, presents cutting-edge research in the field of main group materials and their application, and fundamental investigations into the frustrated Lewis pair interaction. Part 1, which is subject to restricted access, encompasses two chapters. In Chapter 1, an in-depth exploration of new precursor materials for semiconductor doping is detailed. The research, conducted in collaboration with Tokyo Ohka Kogyo Co. Ltd., a prominent Japanese semiconductor technology company, focuses on the development of boron- and phosphorus-containing materials. These materials, synthesized and characterized, hold the promise of advancing the fabrication of nanoscale thin films through spin-coating technology. Chapter 2 delves into the intricacies of the interaction between dopant molecules and surfaces, using advanced quantum methodology, specifically periodic density functional theory applied via the Vienna ab initio Simulation Package code. Part 2 unveils a unique multidisciplinary collaboration between the Melen group (Cardiff University, School of Chemistry), the Browne group (University College London, School of Pharmacy), and the Porch group (Cardiff University, Centre for High-Frequency Engineering). Chapter 3 explores the interaction between Lewis acidic and basic molecules, employing microwave cavity perturbation measurements. This innovative study investigates systems with varying degrees of frustration, using triarylborane species as Lewis acidic components, and pyridine, triarylphosphine, and ether compounds as bases. The aim of this chapter was to begin to develop a quantifiable metric that describes the strength and character of the frustration experienced by certain combinations of acids and bases. This thesis not only expands the understanding of semiconductor doping materials and frustrated Lewis pair chemistry, but also underscores the significance of interdisciplinary collaborations in advancing scientific knowledge. Chapters 1 and 2, although currently under restricted access, promise to contribute significantly to the academic and industrial communities upon their public release in five years (2028).
