- Abstract:
- Supramolecular star-shaped polymers are a class of materials that are formed by self-assembly
of polymeric precursors. The resulting structures combine the beneficial properties of conventional
star-shaped polymers and (reversible) supramolecular interactions. We previously
introduced [2 X 2] copper(I) grids of 3,6-di(2-pyridyl)-
pyridazine (DPP) as structural motif to form
the core of supramolecular star-shaped polymers.
In the current work, this concept is expanded to
star-shaped poly(ethylene glycol) (PEG) by endfunctionalization
of amine-functionalized PEG
with DPP. The synthesis and characterization of
PEG-DPP as well as the self-assembly into starshaped
supramolecular polymers upon copper(I)
complexation are discussed in detail.
