Structural properties of various kinds of room-temperature synthesized C60 fullerene nanowhiskers were investigated by TEM and XRD. The C60 nanowhiskers prepared by use of toluene lost their initial solvated hexagonal structure faster than the C60 nanowhiskers prepared by use of m-xylene. The hexagonal structure of C60 nanowhiskers prepared by use of toluene was stabilized by adding C60[C(COOC2H5)2]. These results suggest that large solute molecules in the C60 nanowhisker matrix stabilize their initially solvated hexagonal structure. Furthermore, the addition of a sufficient amount of C60(2-methoxycarbonyl-N-methylpyrrolidine) into the m-xylene solution of C60 produced the C60 nanowhiskers indicating the formation of ordered solid solution of C60 and C60(2-methoxycarbonyl-N-methylpyrrolidine).
