与传统的自组装策略类似，聚合诱导自组装和重组（PISR）可以通过形态转变产生无数的聚合物形态。除了疏水性嵌段与亲水性嵌段的链长比（R）之外，中间纳米物体中的链移动性（这是形态转变的必要条件）是最终形态形成的决定因素。虽然已经制造了各种形态，但据我们所知，具有高度有序内部结构的六方填充空心环（HHH）还没有通过PISR制备。在这篇文章中，HHH的制备通过从大的复合囊泡到HHH的形态转变的报告。具有高度规整内部结构的六方环在纳米材料的理论研究和实际应用中具有重要意义。
Similar to the traditional self‐assembly strategy, polymerization induced self‐assembly and reorganization (PISR) can produce a myriad of polymeric morphologies through morphology transitions. Besides the chain length ratio (R) of the hydrophobic to the hydrophilic blocks, the chain mobility in the intermediate nano‐objects, which is a requisite for morphology transition, is a determining factor in the formation of the final morphology. Although various morphologies have been fabricated, hexagonally packed hollow hoops (HHHs) with highly ordered internal structure have not, to the best of our knowledge, been prepared by PISR. In this article, the fabrication of HHHs through morphology transition from large compound vesicles to HHHs is reported. HHHs with highly regular internal structure may have significance in theoretical research and practical applications of nanomaterials.
