具有一个或多个圆形空腔的碳纳米环结构代表了球形富勒烯的理想超分子主体,具有形成在固态下作为有机半导体的主客体复合物的潜力。由于形状互补的主体和客体之间的紧密络合,碳纳米环有可能保护富勒烯免受水和氧气的影响,已知水和氧气会干扰电子传输过程。已经发现许多纳米环受体与富勒烯形成主客体复合物。然而,在固态下,对包封的富勒烯的长程有序只有很少或没有控制。因此,这些配合物作为有机半导体的潜力很少被评估。在此,我们提出了所有已知的nanohoop-富勒烯复合物的调查,为获得固态结构。我们讨论并提出的情况下,包含富勒烯客人形成离散的超分子线,这可能会打开它们在电子器件中使用的可能性。 碳纳米环和富勒烯之间的几何互补性使它们能够形成强的超分子主客体复合物。这篇综述文章介绍了所有nanohoop-富勒烯复合物的概况,其中包含富勒烯客体组装成离散的超分子阵列,形成线性或锯齿形一维纳米线,具有作为有机半导体的潜力。
Carbon‐nanohoop structures featuring one or more round‐shaped cavities represent ideal supramolecular hosts for spherical fullerenes, with potential to form host‐guest complexes that perform as organic semiconductors in the solid state. Due to the tight complexation between the shape‐complementary hosts and guests, carbon nanohoops have the potential to shield fullerenes from water and oxygen, known to perturb the electron‐transport process. Many nanohoop receptors have been found to form host‐guest complexes with fullerenes. However, there is only a little or no control over the long‐range order of encapsulated fullerenes in the solid state. Consequently, the potential of these complexes to perform as organic semiconductors is rarely evaluated. Herein, we present a survey of all known nanohoop‐fullerene complexes, for which the solid‐state structures were obtained. We discuss and propose instances where the inclusion fullerene guests form discrete supramolecular wires, which might open up possibilities for their use in electronic devices. The geometric complementarity between carbon nanohoops and fullerenes enables them to form strong supramolecular host‐guest complexes. This Review article presents a survey of all nanohoop‐fullerene complexes, where the inclusion fullerene guests are assembled into discrete supramolecular arrays, forming linear or zigzag one‐dimensional nanowires with potential to perform as organic semiconductors.
