Geometric disassembly of dendritic structures was realized by a cascade cleavage reaction triggered by an initially stimulated group at the dendrimer core. Release of an exponential number of dendrimer fragments was a result of the branching nature of the cleavage pathway. Evidence for the completion of the disassembly process was provided by the absorbance peak of the p-nitrophenoxide ion that was
树枝状结构的几何分解是通过由树枝状聚合物核心处的初始刺激基团触发的级联裂解反应实现的。指数数量的树枝状聚合物片段的释放是裂解途径分支性质的结果。对硝基苯氧离子的吸收峰提供了完成分解过程的证据,该离子为此目的共价安装在树枝的外围。通过树枝状大分子分解释放出指数数量的树枝状大分子片段以改变系统的特性,称为树枝状扩增。
