Polycyclic aromatic compounds (naphthalene, anthracene and pyrene) have been intercalated into the superstructures of fullerene nanowhiskers, using a facile liquid-liquid interfacial precipitation (LLIP) method. Due to the interaction between polycyclic molecules and fullerene, the growth of fullerene crystals was interfered in comparison to the fullerene crystal growth without the polycyclic molecules, resulting in the formation of fullerene superstructures with various nanofeatures. Moreover, the fluorescence emissions of the fullerene superstructures were significantly changed due to the intercalation of the polycyclic molecules, implying the influence of molecular packing on the electron transfer within the nanostructures. These results may bring new insights on the control of fullerene nanostructures and to manipulate their optical properties in optoelectronic devices.
多环芳烃(萘、蒽和芘)已通过一种简便的液-液界面沉淀(LLIP)方法插入到富勒烯纳米晶须的超结构中。由于多环分子与富勒烯之间的相互作用,与没有多环分子时的富勒烯晶体生长相比,富勒烯晶体的生长受到干扰,从而导致形成具有各种纳米特征的富勒烯超结构。此外,由于多环分子的插入,富勒烯超结构的荧光发射发生了显著变化,这意味着分子堆积对纳米结构内电子转移的影响。这些结果可能为富勒烯纳米结构的控制以及在光电器件中操纵其光学性质带来新的见解。
