- Abstract:
- 2,2’-Bipyridines functionalized with one bromomethyl group in
the 5-position were used as metallo-supramolecular initiators for
the living cationic polymerization of 2-oxazolines utilizing
cobalt(II), iron(II) and ruthenium(II) transition metal ions. The
central metal ions could be removed using basic conditions
resulting in uncomplexed polymers with a free metal binding
side. The obtained polymers were characterized using NMR,
UV/Vis spectroscopy, GPC and MALDI-TOF mass spectrometry.
The termination of the living end groups with an amino-functionalized
terpyridine during the polymerization process opens
the possibility for the construction of polymers with different
metal binding sides. Due to the exact control of molecular weight, defined end groups and the variability of the oxazoline
monomers new supramolecular polymers can be obtained.
