Two molecular Janus particles based on amphiphilic [60]fullerene (C 60 ) derivatives were designed and synthesized by using the regioselective Bingel–Hirsh reaction and the click reaction. These particles contain carboxylic acid functional groups, a hydrophilic fullerene (AC 60 ), and a hydrophobic C 60 in different ratios and have distinct molecular architectures: 1:1 (AC 60 –C 60 ) and 1:2 (AC 60 –2C 60 ). These molecular Janus particles can self‐assemble in solution to form aggregates with various types of micellar morphology. Whereas vesicular morphology was observed for both AC 60 –C 60 and AC 60 –2C 60 in tetrahydrofuran, in a mixture of N , N ‐dimethylformamide (DMF)/water, spherical micelles and cylindrical micelles were observed for AC 60 –C 60 and AC 60 –2C 60 , respectively. A mechanism of formation was tentatively proposed based on the effects of molecular architecture and solvent polarity on self‐assembly.
