Assessment of Fullerene Derivatives as Rolling Journals in a Finite Carbon Nanotube Bearing

Conformance assessment of rolling journals in a molecular bearing has been carried out with a combination of fullerenes and finite single-wall carbon nanotube molecules through quantitative analysis of the binding affinities. Endohedral fullerenes were applicable to three-body molecular bearings with slightly weaker binding affinities. Exohedral shaft moieties on C₆₀ journals affected the binding affinities to reduce the binding constants to a considerable extent, and oval-spherical C₇₀ journals were superior in tolerating bulky shaft attachments

Asymmetric Autocatalysis Initiated by Finite Single-Wall Carbon Nanotube Molecules with Helical Chirality

An asymmetric autocatalysis reaction was initiated by a finite single-wall carbon nanotube molecule with helical chirality. The asymmetric induction was initiated by the chiral environment arising from the planar chirality of the tubular polyaromatic hydrocarbons

Photoinduced Electron Transfer in a Dynamic Supramolecular System with Curved π‑Structures

Photoinduced electron-transfer processes in a carbonaceous supramolecular combination of a tubular host and a C₆₀ guest were investigated with time-resolved transient absorption spectra upon laser flash photolysis. Following the formation of triplet charge-separated species via electron transfer from the host to the guest, a rapid back electron transfer proceeded to afford triplet C₆₀
