The unique self‐assembling features of N‐annulated perylene bisimides (PBIs) 1 and 2 are reported. The stability of the aggregates of diester 1 , in which no H‐bonding interactions are operative, corroborates the significance of long‐range van der Waals and dipole–dipole electrostatic interactions in the construction of stable supramolecular assemblies. The incorporation of amide functional groups within the N‐annulated PBI in 2 stimulates pathway differentiation to achieve up to three J‐type aggregates and a fourth H‐type aggregate depending on the experimental conditions. The results presented demonstrate unprecedented levels of control over synthetic supramolecular self‐assembly and the rich differentiation that N‐annulated PBIs exhibit, opening the door to new, complex, functional supramolecular materials. 相似文献

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. 相似文献
