Complexes of ditopic and tritopic 4'-substituted- 2,2':6',2''-terpyridine ligands

Chapter 1 gives a brief introduction to supramolecular chemistry, metallosupramolecular
chemistry and 2,2':6',2''-terpyridine-based ligands and their complexes.
Chapter 2 discusses the synthesis and characterization of new ditopic ligands L1-L4 and
L6-L7. These ligands are based on a benzene unit connected to two 4'-substituted-
2,2':6',2''-terpyridine moieties through polyethyleneoxy spacers. The variability of this
group of compounds was achieved by using different length ethyleneoxy chains and
changing the substitution position on the benzene unit. The ligands were also preliminary
studied for interactions with Group 1 metals.
Chapter 3 describes the synthesis and characterization of heteroleptic dinuclear
ruthenium(II) complexes formed with ligands L1-L2, L4 and L6-L7.
Chapter 4 describes the synthesis and characterization of a homoleptic mononuclear
zinc(II) complex with a ditopic 4'-substituted- 2,2':6',2''-terpyridine ligand L4.
Chapter 5 discusses the synthesis and characterization of ligand L5 which contain three
2,2':6',2''-terpyridine metal-binding domains as well as the synthesis and characterization
of a heteroleptic trinuclear ruthenium(II) complex of this ligand. Three 2,2':6',2''-
terpyridine domains on the ligand L5 are linked at their 4'-positions to a benzene unit
through diethylene glycol spacers.
Chapter 6 describes the synthesis and characterization of homoleptic mononuclear
europium(III) and terbium(III) complexes of tritopic 4'-substituted- 2,2':6',2''-terpyridine
ligand L5.
