An iterative step-by-step synthetic approach is employed to form perylene bisimide (PBI) oligomers of defined sizes by connecting the PBI units through their imide positions via a benzyl linker. The versatility of this approach was showcased by its successful implementation on two different PBI building blocks to achieve two separate series of oligomers (up to the pentamer) with modulated conformations: one with an open random coil oligomer and one with an H-type foldamer architecture.

两类苝双酰亚胺低聚物的顺序合成及二级结构分析

采用迭代逐步合成方法，通过苄基连接体通过其酰亚胺位置连接 PBI 单元，形成指定尺寸的苝双酰亚胺 (PBI) 低聚物。该方法的多功能性通过在两种不同的 PBI 构建模块上的成功实施来展示，以实现具有调制构象的两个独立系列的低聚物（直至五聚体）：一种具有开放的无规卷曲低聚物，另一种具有 H 型折叠体结构。
