Miktoarm star polymers are a particular type of branched
polymers
featuring a star-shaped architecture with arms based on different
polymer types. Such materials exhibit unique thermal, mechanical,
and self-assembly properties. Hence, this polymer class is of great
interest in different research fields. So far, the synthesis of these
entities can be rather challenging, particularly applying covalent
strategies for linking of the different polymers. Thus, an approach
for the synthesis of such polymer architectures is presented using
orthogonal metal–ligand interactions to connect the different
building blocks, resulting in a miktoarm topology. The obtained structures
are investigated via diffusion-ordered nuclear magnetic resonance
spectroscopy, by analytical ultracentrifugation and dynamic light
scattering.
