One-Pot Synthesis of Miktoarm Star Polymers Based on Orthogonal Metal–Ligand Interactions

This is the authors' abstract. We don't add key points for this paper.

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.
