- Abstract:
- A Williamson type etherification approach was applied for the reaction of 4'-chloro-
2,2':6',2''-terpyridine with a number of well-defined mono- and bis-hydroxy functionalized
polymers, namely poly(tetrahydrofuran), poly(2-ethyl-2-oxazoline) and Pluronics. The
resulting terpyridine functionalized polymers were characterized by 1H NMR spectroscopy
and SEC, as well as MALDI-TOF-MS demonstrating the successful functionalization. This
type of end-functionalized chelating macromolecules could be considered as key candidates
for the preparation of metallo-supramolecular polymers via metallo-terpyridine
complexation; the principle feasibility was demonstrated by UV–vis titration of iron(II)
chloride to bis-terpyridine functionalized poly(tetrahydrofuran).
