- Abstract:
- Metallo-supramolecular polymers offer attractive possibilities to combine the properties of
polymers with the characteristics offered by the metal–ligand coordination. Here we present
for the first time the combination of metal-bis(terpyridine) complexes and lower critical
solution temperature (LCST) polymers that can
be switched by addressing either the thermosensitive
polymer or the metal complex. We
describe a new strategy for the synthesis
of poly(N-isopropylacrylamide) (PNIPAM) end
functionalized with a terpyridine moiety, which
is further used for the preparation of FeII
and ZnII-bis(terpyridine PNIPAM). The comparison
of the LCST behavior of the uncomplexed
ligands and their metal complexes that bear
different counter ions is included. Furthermore,
the switchability of the synthesized FeII system
is demonstrated by a decomplexation reaction
followed by the characterization of the uncomplexed
ligand.
