Photophysical properties of polynuclear complexes containing phenylpyridine-iridium(III) units (IR)

The content of this thesis is concerned with twofold areas of research: i) the synthesis of various types of bis(phenylpyridine) iridium(III) dicyanide complexes, and studies of their structural and photophysical behaviour; ii) the synthesis and studies of iridium(III) complexes, containing two fluo...
