Abstract:
The work described in this thesis has three main aims (a) to develop novel methods for the formation of metallochlorophyllins. (b) to examine the kinetics and mechanism of metal complex formation. (c) to examine the effect of the metal ion on the spectroscopic properties of the chorophyllins. The opening section describes the development of methods for the formation of metallochlorophyllins. In the first part of this section, the method of formation of copper chlorophyllin is examined, with the determination of the optimum point to add the metal salt and the purity of the final product. In the second part, the method of formation of other metallochlorophyllins is examined. In the second section, the I.R. and far-infrared spectra of metallochlorophyllins are discussed, the effect of the central ion and method of preparation on the vibrational bands. The third section describes the kinetics and mechanism of metallochlorophyllin formation in aqueous and non-aqueous solution. Thermodynamic, kinetic and photochemical stability series are constructed. In the fourth section, the FAB mass spectra of metallochlorophyllins are discussed and the effect of the central ion on the fragmentation pattern.
