Studies were carried out on the hierarchical self‐assembly versus pathway complexity of N‐annulated perylenes 1–3, which differ only in the nature of the linking groups connecting the perylene core and the side alkoxy chains. Despite the structural similarity, compounds 1 and 2 exhibit noticeable differences in their self‐assembly. Whereas 1 forms an off‐pathway aggregate I that converts over time (or by addition of seeds) into the thermodynamic, on‐pathway product, 2 undergoes a hierarchical process in which the kinetically trapped monomer species does not lead to a kinetically controlled supramolecular growth. Finally, compound 3, which lacks the amide groups, is unable to self‐assemble under identical experimental conditions and highlights the key relevance of the amide groups and their position to govern the self‐assembly pathways.

N环Per中的途径复杂性与分层自组装：种子超分子聚合中的结构效应

研究，在N个-环苝的层次自组装与途径的复杂性进行1 - 3，不同之处仅在连接苝芯和烷氧基链的一侧的连接基团的性质。尽管结构相似，化合物1和2在自组装方面仍表现出明显的差异。而1种形式的偏离路径集合体我，其将随时间（或通过添加种子的）转换成热力学上途径产物，2所经历分级方法，其中动力学捕获单体种类不会导致动力学控制的超分子的增长。最后，化合物3缺少酰胺基的烷烃在相同的实验条件下无法自组装，并突出了酰胺基的关键相关性及其在支配自组装途径中的位置。
