Supramolecular interactions between molecules of the same or different nature determine to a great extent the degree of their applicability in many fields of science. To this regard, planar polycyclic aromatic hydrocarbons (PAHs) and their nanometric congeners, nanographenes (NGs), as well as positively curved ones, as for instance corannulene, have been extensively explored. However, negatively curved saddle-shaped NGs have remained a curiosity to date within this field. Therefore, here we communicate the first systematic study on the supramolecular behavior of heptagon-containing hexa-peri-hexabenzocoronene analogues. Thus, their self-association and host–guest complexation processes with both flat and curved PAHs, and fullerenes have been studied by means of ¹H and ¹³C NMR titrations in solution, identifying C₇₀ as one of the guests with the highest association constant among all the ones tested.

相同或不同性质的分子之间的超分子相互作用在很大程度上决定了它们在许多科学领域中的适用程度。为此，已经广泛地研究了平面多环芳族烃（PAH）及其纳米同类物，纳米石墨烯（NG）以及正向弯曲的芳族烃，例如cor喃环烯。然而，迄今为止，负弯曲的鞍形天然气发动机仍是该领域的好奇心。因此，我们在这里交流含七边形，六的超分子行为的第一个系统研究围-hexabenzocoronene类似物。因此，通过¹ H和¹³研究了它们在平面和弯曲PAHs和富勒烯之间的自缔合和主客体络合过程。溶液中的C NMR滴定，确定C ₇₀为所有被测物中缔合常数最高的客体之一。
