The semibatch BrO₃⁻–SO₃²⁻ pH oscillator serves as the radical source for the in situ polymerization of the pH-responsive 2-(diisopropylamino)-ethyl methacrylate monomer on poly(ethylene-glycol)-macroCTA chain and generates an amphiphilic block copolymer. These building blocks concurrently self-assemble to micelles and then transforms to vesicles as the chain length of the hydrophobic block growths. Large amplitude oscillations in the concentration of H⁺ by the semibatch BrO₃⁻–SO₃²⁻ are provoked when the conditions in the system are favorable. The oscillations control the protonation state of the tertiary amine group in the core segment of the block copolymer. Rhythmic assembly-disassembly of the polymer structures is observed. All processes, from the time- regulated autonomous formation of the building blocks, their self-assembly and the rhythmic disassembly-reassembly are governed by the same simple chemical system, in the same reaction vessel, without complicated multi step procedures and are fueled and kept out of equilibrium by the uniform inflow of SO₃²⁻.

通过化学pH振荡器同时自我调节pH响应大囊泡的自主合成和功能化

半批式BrO ₃ ^-- SO ₃ ^2- pH振荡器是自由基反应源，用于在聚（乙二醇）-macroCTA链上原位聚合pH响应性的2-（二异丙基氨基）-甲基丙烯酸乙酯单体，并生成两亲性嵌段共聚物。这些结构单元同时自组装成胶束，然后随着疏水性单元段链长的增长而转变为囊泡。半批BrO ₃ ^-- SO ₃ ^2-引起的H ⁺浓度的大幅度振荡当系统中的条件良好时，将触发该命令。振荡控制了嵌段共聚物的核心链段中叔胺基的质子化状态。观察到聚合物结构的有节奏的组装-分解。从受时间限制的自动生成结构块，它们的自组装和有节奏的拆卸-重新组装，所有过程都由同一简单的化学系统在同一反应容器中进行控制，而无需复杂的多步骤程序，并且可以加油并保存由于SO ₃ ^2-的均匀流入而失去平衡。
