Abstract

The synthesis of chiral functional nanocarbons with an intense chiroptical response has been a great topic of interest. For instance, making a chiral orifice on [60]fullerene is an attractive way to access functional chiral nanocarbons since the thus-obtained chiral chromophores potentially work as hosts for certain guests. However, it has been less explored how the guests make an impact to chiral properties of the hosts. In this paper, we examined an effect of a water guest placed inside a chiral [60]fullerene host, revealing strengthened chiral recognition by sugar as well as largely perturbed electronic transitions from ground to higher-energy excited states. We also discussed significant alteration of chiroptical parameters which rely upon thermally-allowed geometrical displacement of the orifice.

刚性手性纳米碳宿主：它的性质会受到客体的干扰吗？

具有强烈手性反应的手性功能纳米碳的合成一直是人们感兴趣的一个重要课题。例如，在[60]富勒烯上制造手性孔是获得功能性手性纳米碳的一种有吸引力的方法，因为由此获得的手性发色团可能作为某些客体的宿主。然而，对于访客如何影响宿主的手性，研究较少。在本文中，我们研究了放置在手性[60]富勒烯宿主体内的水客体的影响，揭示了糖的手性识别增强以及从基态到高能激发态的大量扰动电子跃迁。我们还讨论了热学参数的重大变化，这取决于热允许孔的几何位移。

期刊介绍： The journal Carbon is an international multidisciplinary forum for communicating scientific advances in the field of carbon materials. It reports new findings related to the formation, structure, properties, behaviors, and technological applications of carbons. Carbons are a broad class of ordered or disordered solid phases composed primarily of elemental carbon, including but not limited to carbon black, carbon fibers and filaments, carbon nanotubes, diamond and diamond-like carbon, fullerenes, glassy carbon, graphite, graphene, graphene-oxide, porous carbons, pyrolytic carbon, and other sp2 and non-sp2 hybridized carbon systems. Carbon is the companion title to the open access journal Carbon Trends. Relevant application areas for carbon materials include biology and medicine, catalysis, electronic, optoelectronic, spintronic, high-frequency, and photonic devices, energy storage and conversion systems, environmental applications and water treatment, smart materials and systems, and structural and thermal applications.
