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 × 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 end-functionalization of amine-functionalized PEG with DPP. The synthesis and characterization of PEG-DPP as well as the self-assembly into star-shaped supramolecular polymers upon copper(I) complexation are discussed in detail.
超分子星形聚合物是一类由聚合物前体自组装形成的材料。所得结构结合了传统星形聚合物的有益特性和（可逆的）超分子相互作用。我们之前引入了3,6-二（2-吡啶基）哒嗪（DPP）的[2×2]铜（I）网格作为结构基序，以形成超分子星形聚合物的核心。在当前工作中，通过用DPP对胺官能化的聚乙二醇（PEG）进行端官能化，将这一概念扩展到了星形聚乙二醇（PEG）。详细讨论了PEG-DPP的合成与表征以及在铜（I）络合后自组装成星形超分子聚合物的过程。
