Abstract:
This thesis describes the realisation of an ultraviolet photoelectron spectrometer for both gaseous and solid samples in addition to photoelectron spectroscopic studies of phthalocyanine pigments using both the ultraviolet (UPS) and the X-ray (XPS) techniques. A historical and general introduction to both photoelectron spectroscopy and phthalocyanine pigments, including the economic importance of the latter, is followed by a comprehensive description of the work carried out on the instrument and its component parts. The performance of the instrument with both gaseous and solid samples is then discussed. The molecular and crystal structures of phthalocyanines are reviewed along with the relationships between the crystal modifications of copper phthalocyanines and pigmentary properties. Theoretical studies on the electronic structures of copper phthalocyanine are examined prior to the interpretation and assignment of the UPS spectra of copper phthalocyanine. Traces of different species on the surface of copper phthalocyanine pigments, due to the different "finishing" treatments undergone by the pigments, were examined by XPS of different commercial and laboratory prepared samples. The final chapter summarises the conclusions drawn from the work.
