Single-crystalline C
60·1
m-xylene nanorods with a hexagonal structure were successfully synthesizedby evaporating a C
60 solution in
m-xylene at room temperature. The ratio of the length to the diameterof the nanorods can be controlled in the range of

10 to over 1000 for different applications. Thephotoluminescence (PL) intensity of the nanorods is about 2 orders of magnitude higher than that forpristine C
60 crystals in air. Both UV and Raman results indicate that there is no charge transfer betweenC
60 and
m-xylene. It was found that the interaction between C
60 and
m-xylene molecules is of the vander Waals type. This interaction reduces the icosahedral symmetry of C
60 molecule and induces strongPL from the solvate nanorods.
