We performed bending tests on crystalline whiskers composed of fullerene C60 molecules by in situ transmission electron microscopy with simultaneous measurement of the applied force by an optical deflection method. A C60 nanowhisker with a diameter of 123 nm was fixed on two fulcra and a concentrated force was applied on the midpoint between the fulcra by the piezomanipulation of a silicon nanotip. The Young's modulus of the nanowhisker was estimated to be 53–69 GPa, 72% smaller than that of C60 nanotubes. The estimated Young's modulus was plotted against the outer diameter along with the moduli estimated previously by buckling tests on C60 nanowhiskers. In this relationship, Young's modulus increased as the outer diameter decreased. The result was in agreement with the core–shell model for C60 nanowhiskers.
