Abstract
All known methods for fullerene synthesis produce a variety of Cn molecules, indicating that fullerene with other sizes than C60 exist and can be stable. However, the range and variety of those molecules is largely unexplored. It is also unknown if there is an upper limit for n. The size and the shape of those molecules become crucial when they are surrounded by a gas or a liquid since the molecules are exposed to elevation force and pressure. The resistance to pressure and the elevation force are the highest if the shape is spherical. Spherical or almost spherical shape can be achieved if the carbon network includes a certain amount of defects (pentagon-heptagon rings). Those spherical structures can be expected since computer simulation of the Cn growth predicts that the number of the defects is significant during the synthesis. In this paper we show that spherical Cn structures, which are large enough to be lighter than air, can potentially withstand atmospheric pressure.
