this architecture, the divergent "graft-from" and the convergent click "graft-to" approaches, are explored and the resulting products fully characterized. This route is particularly attractive because it enables production of exact linear and cyclic dendronized analogues, enabling direct comparison of their physical properties. In this preliminary work, the divergent "graft from" approach appears to
环状树枝状聚合物代表了一类新的聚合物,其表现出类似甜甜圈的“环形”形状。探索了两种以前未报告的用于准备此架构的方法,即发散的“graft-from”和会聚点击“graft-to”方法,并充分表征了由此产生的产品。该路线特别有吸引力,因为它能够生产精确的线性和环状树枝状类似物,从而能够直接比较它们的物理特性。在这项初步工作中,不同的“接枝自”方法似乎导致材料在高 DP 下具有宽 PDI,而“接枝到”方法在较大 DP 下产生更明确的树枝状环状聚合物。根据迄今为止的报告,点击环化然后点击“嫁接”的组合
