- Abstract
Two molecular Janus particles based on amphiphilic [60]fullerene (C60) 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 (AC60), and a hydrophobic C60 in different ratios and have distinct molecular architectures: 1:1 (AC60-C60) and 1:2 (AC60-2C60). 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 AC60-C60 and AC60-2C60 in tetrahydrofuran, in a mixture of N, N-dimethylformamide (DMF)/water, spherical micelles and cylindrical micelles were observed for AC60-C60 and AC60-2C60, respectively. A mechanism of formation was tentatively proposed based on the effects of molecular architecture and solvent polarity on self-assembly.
