- Abstract:
- The molecular weight of an extended metallo-supramolecular polymer,
based on a α,ω-bis-terpyridine-poly(ethylene glycol) polymer linked via
ruthenium(II) ions, was determined by gel permeation chromatography,
viscosimetry as well as analytical ultracentrifugation. An optimized GPC method
was applied for the first time to this kind of chain extended supramolecular
polymers and the obtained results showed a good agreement with viscosimetry
and analytical ultracentrifugation. A chain extended polymer with an average
molecular weight of around 140 000 was found. These results clearly demonstrate
that well-soluble high-molecular-weight metal-containing coordination polymers
that are based on well-defined telechelics can be synthesized and fully
characterized.
