Intramolecular non-covalent interactions between aromatic ligands in chiral Ru(II) and Co(III) complexes have been investigated in this study. Several investigations were carried out and findings given. The results of the study, which demonstrate the significance of non-covalent interactions involving aromatic residues to the determination of the molecular conformation, serve to highlight the suitability of simple chiral metal complexes to act as models for interactions / Doctor of Philosophy (PhD)

It is important to be able to quantify potential seismic damage to structures and communicate risk in a comprehendible way to all stakeholders. The risks involved with damage to constructed facilities due to catastrophic disasters can be hedged using financial instruments such as Catastrophic (CAT) bonds. This work uses the loss ratio (Lr), which is the ratio of the repair cost to the total replacement cost, to represent structural and non-structural damage caused by earthquakes. A loss estimation framework is presented that directly relates seismic hazard to seismic response to damage and hence to losses. A key feature of the loss estimation approach is the determination of losses without the need for fragility curves. A Performance-Based Earthquake Engineering (PBEE) approach towards assessing the seismic vulnerability of structures relating an intensity measure (IM) to its associated engineering demand parameter (EDP) is used to define the demand model. An empirically calibrated tripartite loss model in the form of a power curve with upper and lower cut-offs is developed and used in conjunction with the previously defined demand model in order to estimate loss ratios. The loss model is calibrated and validated for different types of bridges and buildings. Loss ratios for various damage states take into account epistemic uncertainty as well as an effect for price surge following a major hazardous event. The loss model is then transformed to provide a composite seismic hazard-loss relationship which is used to estimate financial losses from expected structural losses. The seismic hazard-loss model is then used to assess the expected spread, that is the interest rate deviation above the risk-free (prime) rate in order to price two types of CAT bonds: indemnity CAT bonds and parametric CAT bonds. It is concluded that CAT bonds has the ability to play a major role in hedging financial risk associated with damage to a civil engineering facility as a result of a catastrophe. However, it is seen that a potential investor seeks a high degree of confidence when investing in CAT bonds as there is huge uncertainty surrounding the probability of occurrence of an event.

Abstract As Convertible Bonds (CB) market increasingly prospers in recent years, not only has it become one of the most important financing tools for public firms, but also the popular investment target for investors. However, given the complexity of Convertible Bonds Issuance Terms, coexistence of new and old regulations, and difficulties in obtaining relevant information, investors know little about CB in terms of its investment restrictions as well as arbitrage opportunities and models. This study attempts to explore arbitrage strategies for CB¡¦s trading and investing, and to design a CB ¡§Information System¡¨ which severs as a CB database querying system, and helps enhance the efficiency of CB investment and arbitrage. In this study, three CB related information systems were developed after analyzing CB issuance information and market price: 1. ¡§Database Querying System,¡¨ which is used to search for arbitrage restrictions and related information before engaging in CB investment and arbitrage. 2. ¡§Put Provision Instant Quoting System,¡¨ which is able to receive market quotation before exchange deadline, and to instantly calculate the rate of return in put provision. 3. ¡§Arbitrage Instant Quoting System,¡¨ like ¡§Put Provision Instant Quoting System,¡¨ can promptly calculate the rate of return in CB and considerably increase operating efficiency and the rate of return in arbitrage. Based on the case study and empirical research, this study argues that these three information systems can practically help control the fluctuation of market price, enhance operating efficiency, and serve as an effective financial operating tool of CB arbitrage strategies. Accordingly, several conclusions of this study are presented as follows: 1. The current stock market is inefficient, so the arbitrage opportunities are still available. 2. When market is thriving and stock price exceeds CB price, there are more arbitrage opportunities for and higher rate of return in CB. 3. While investing put provision for CB often accompanies high return opportunities, investors are suggested to gingerly evaluate the finance risks of public firms beforehand, such as making use of ¡§Instant Quoting System¡¨ to operate, which is helpful to controlling market price effectively. 4. To avoid operating risks, Investors should recognize all kinds of issuance restrictions in advance. 5. Conducting ¡§Instant Quoting System¡¨ can obtain market information quickly and promote operation efficiency and the rate of return.

This dissertation concerns the discovery of the ability of the guanidinate ligand hpp (hpp = anion of 1,3,4,6,7,8-hexahydropyrimido[1,2-a]pyrimidine) to stabilize high oxidation states of dimetal units (particularly dimolybdenum species) and attempts to control solubility and redox potential through modification of the ligand. Two general strategies were used for the ligand modifications: alteration of the ring size, and addition of alkyl substituents. All of the dimetal complexes using these ligands show a significant shift in redox potential compared to other commonly used classes of ligands (i.e. carboxylates and formamidinates) allowing access to the Mo2 4+, Mo2 5+ and Mo2 6+ oxidation states. The solubility of the complexes increases with increasing ring size, or with increasing length of the alkyl substituent. The physical and chemical properties of the ligands and their dimolybdenum complexes are described in detail.
