Abstract Post-cleavable block copolymer is a very important class of materials, especially for the preparation of nanochannel materials. Block copolymers can self-assemble to various nanostructures. By adding specific groups between two blocks, we can obtain the materials we need. Here, we synthesized a block copolymer with acid-cleavable junction. Polyethylene oxide and polymethyl methacrylate with chalcone structure （PEO-Ac-PChal）were synthesized by atom transfer radical polymerization (ATRP). After the acetal structure is acidified, one of the blocks was dissolved by a specific solvent, and the nanochannel structure was prepared.

基于嵌段共聚物的稳定有序纳米通道，具有酸可裂解结和紫外交联基团

摘要 可裂解后嵌段共聚物是一类非常重要的材料，特别是用于制备纳米通道材料。嵌段共聚物可以自组装成各种纳米结构。通过在两个块之间添加特定的组，我们可以获得我们需要的材料。在这里，我们合成了一种具有酸可裂解连接的嵌段共聚物。采用原子转移自由基聚合（ATRP）合成了聚环氧乙烷和具有查耳酮结构的聚甲基丙烯酸甲酯（PEO-Ac-PChal）。缩醛结构酸化后，将其中一个嵌段用特定溶剂溶解，制备出纳米通道结构。
