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.
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.
