Construction of Thermo-setting Phenolic Resin Containing Sliding Unit Segments

我们首次尝试合成高分子量紫精聚合物。然而，由于阳离子反应的低反应性，聚合度(DP)被发现为8-10。因此，我们合成了含聚四氢呋喃的另一柱[5]芳烃基聚轮烷。通过在带有10个三环氧乙烷链的液体柱[5]芳烃中用笨重的塞子封盖聚四氢呋喃端基，可以合成由带有10个三环氧乙烷链的柱[5]芳烃轮和聚四氢呋喃组成的新型非离子聚轮烷。

We firstly tried to synthesize viologen polymers with high molecular weights. However, due to the low reactivity of the cationic reaction, the degree of polymerization (DP) was found to be 8-10. Thus, we synthesized the other pillar[5]arene-based polyrotaxanes containing polyTHF. By capping polyTHF end groups with bulky stoppers in liquid pillar[5]arene carrying 10 triethylene oxide chains, new nonionic polyrotaxanes consisting of polyTHF and pillar[5]arene wheels carrying 10 triethylene oxide chains could be synthesized.
