“…A carbon nanobelt (CNB) is a loop of fused benzene rings and various types of CNBs have been successfully synthesised in recent years 1 – 7 . The structures of CNBs, structural transitions and the effect of external electric fields on the structures of CNBs have been theoretically and numerically analysed 8 – 11 and several devices, in which CNBs are used, have been designed and developed 12 – 14 . A C 60 molecule is one form of fullerenes composed of 60 carbon atoms 15 .…”

It was previously shown that spherical particles are self-assembled by compounds composed of C60-(6,6)CNB-C60, where CNB stands for “carbon nanobelt”, by mixing two individual solutions of C60 and (6,6)CNB molecules dissolved in 1,2-dichlorobenzene at room temperature. The particles are monodisperse in water thanks to their high absolute value of the zeta potential in water. In this report, we investigate the effect of thermal treatment of the particles on some changes in the physical properties and structures. We find that the particles become electrically conductive after thermal treatment at 600 °C for 1 h. We suppose that the change in the electrical characteristics might have been caused by the structural change of (6,6)CNBs into opened-up ribbons composed of fused benzene rings, which construct networks supported by C60 molecules in the particles, judging by the change in the absorption and mass spectra of the particles after thermal treatment and analysis of a possible change in the structure of C60-(6,6)CNB-C60 based on quantum chemical calculations employing the PM6 method, with which it is known that nanostructures such as carbon nanotubes (CNTs) and (6,6)CNBs can be correctly estimated.
