New oligopyridine ligands for transition metal complexes and their applications

This thesis concerns the synthesis of polypyiridine ligands, their use for preparation of
transition metal complexes and finally, the application of the transition metal complexes for
Dye Sensitized Solar Cells (DSCs) and Light Emitting Electrochemical Cells (LECs).
Chapter 1 gives a short introduction of the ligands, the metal complexes which were
involved in this work, as well as, their applications.
Chapter2 defines the objectives of this work.
Chapter 3 describes the synthetic approaches to new polypyridine ligands with either the
classical KRÖHNKE method or with less used and for some substituents not reported methods.
These include direct coupling of lithium organyls or the Jahng reaction, followed by the
discussion of their characterization and properties.
Chapter 4 describes the synthesis of homoleptic copper(I) complexes and their
characterization. Difficulties with NMR experiments and the reason thereof are discussed in
detail along with electrochemical experiments. Their use in the preparation of DSCs is given
at the end of this chapter.
Chapter 5 regards the synthesis and characterization of novel iridium(III) complexes, as well
as, the results for some LECs devices.
Chapter 6 shows the results obtained with novel ruthenium(II) complexes based on new bpy
or tpy ligands, respectively. ----------
