Solubility and transformation of fullerene C60 molecule

Abstract

This paper deals with the research of solubility of fullerene C60 molecule and from our investigation we have concluded that the degree of solubility of fullerene molecules depends on their chemical activity and their chemical activity is defined by the energy state of fullerene molecule. Among the set of states three ground resonance structures (A, B, C) are in existence in fullerene molecule. In our opinion the extremality of solubility of molecule C60 near the room temperature is explained by the structure change of double bonds in fullerene frame. These bonds status modify the chemical activity of molecule C60 and consequently the capacity to add the different amount of solvent molecules. The status of double bonds depends on the state and interaction of pentatomic molecules, forming the frame of molecule C60, with each other. Here we show that on cooling the five atomic molecules in the C60 frame transform from the state of radialene into pentaene and then into pentadiene. In the course of this process the double bonds in the C60 frame are turned from extramolecular to intramolecular for five atomic molecules. This conclusion follows from the physical and chemical features of effects observed both in a solid and in solution for the definite interval of temperatures.
