A needle crystal in the form of a capsule comprising fullerene molecules such as C60 and a C60-platinum derivative and having a hollow portion (a fullerene shell capsule) is provided. The fullerene shell capsule which has been prepared by the liquid-liquid interface deposition method, which comprises (1) a step of allowing a solution having a first solvent containing fullerene dissolved therein to meet with a second solvent having less solubility for fullerene than that of the first solvent, (2) a step of forming a liquid-liquid interface between the above solution and the above second solvent and (3) a step of depositing a carbon fine wire in the above liquid-liquid interface, has a novel characteristic in its form and can be used as a material for carrying a catalyst, a raw material for a plastic composite material, a material for the storage of a gas such as hydrogen, a catalyst for use in a fuel cell, or the like. Further, provided are a novel C60-C70 mixed fine wire which is a fullerene fine wire comprising two components of C60 and C70; and a method for preparing the mixed fine wire. |
