Special Issue Information

Dear Colleagues,

The discovery of C60 fullerene in 1985 marked the initiation of research into nanoscale carbon-based materials. Over the ensuing three decades, a succession of various allotropes, including carbon nanotubes, graphene, nanodiamonds, and graphdiyne, were meticulously synthesized. Thanks to their distinctive geometrical and electronic structures, nanocarbon materials have been extensively applied across diverse fields, such as semiconductors, photovoltaic devices, life science, energy science, and catalysis. As early as 1970, Eiji Osawa envisioned the theoretical existence of C60, validating its molecular design and property prediction through theoretical calculations. Presently, with the progress in quantum chemistry and ab initio molecular dynamics, theoretical calculations have become indispensable tools for comprehending nanocarbon materials. They aid in explaining formation mechanisms, analyzing physical and chemical properties, and predicting functional applications. Furthermore, the evolution of artificial intelligence technology empowers researchers to amass vast amounts of high-precision computational data for constructing the structure–property relationships in nanocarbon materials. This facilitates the reverse design of materials and the training of machine-learning potentials for extended-time-scale and complex system dynamic simulations.

Given this history, we invite researchers to contribute original articles and reviews in this Special Issue titled “Theoretical Research of Carbon Nanomaterials.” The potential topics encompass, but are not confined to: novel nanocarbon materials and formation mechanisms, the design of nanocarbon-based catalysts and catalytic mechanisms, computations elucidating the photochemical and photophysical processes in nanocarbon-based photovoltaic devices, and the application of machine-learning approaches in studying nanocarbon materials.

Tri-metallofullerenes, specifically M3@C80 where M denotes rare-earth metal elements, are molecules that possess intriguing magnetic properties. Typically, only one metal element is involved in a given tri-metallofullerene molecule. However, mixed tri-metallofullerenes, denoted as M1xM23-x@C80 (x = 1 or 2, M1 and M2 denote different metal elements), have not been previously discovered. The investigation of such mixed tri-metallofullerenes is of interest due to the potential introduction of distinct properties resulting from the interaction between different metal atoms. This paper presents the preparation and theoretical analysis of mixed rare-earth tri-metallofullerenes, specifically YxDy3−x@C80 (x = 1 or 2). Through chemical oxidation of the arc-discharge produced soot, the formation of tri-metallofullerene cations, namely Y2Dy@C80+ and YDy2@C80+, has been observed. Density functional theory (DFT) calculations have revealed that the tri-metallofullerenes YxDy3−x@C80 (x = 1 or 2) exhibit a low oxidation potential, significantly lower than other fullerenes such as C60 and C70. This low oxidation potential can be attributed to the relatively high energy level of a singly occupied orbital. Additionally, the oxidized species demonstrate a large HOMO-LUMO gap similar to that of YxDy3−xN@C80, underscoring their high chemical stability. Theoretical investigations have uncovered the presence of a three-center two-electron metal–metal bond at the center of Y2DY@C80+ and YDy2@C80+. This unique multi-center bond assists in alleviating the electrostatic repulsion between the metal ions, thereby contributing to the overall stability of the cations. These mixed rare-earth tri-metallofullerenes hold promise as potential candidates for single-molecule magnets. Full article
