摘要

通过苄基连接剂将 PBI 单元通过其酰亚胺位置连接起来，从而采用迭代分步合成法形成具有确定尺寸的过烯双亚胺（PBI）低聚物。通过在两种不同的 PBI 构建模块上成功实施这种方法，实现了两个独立系列的低聚物（直到五聚体）的调控构象：一个是开放式无规线圈低聚物，另一个是 H 型折叠结构。

Sequential Synthesis and Secondary Structure Analysis of Two Classes of Perylene Bisimide Oligomers

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.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
