Abstract

The solubility of pristine fullerenes can be enhanced by mixing C₆₀ and C₇₀ due to the associated increase in configurational entropy. This "entropic dissolution" allows the preparation of field-effect transistors with an electron mobility of 1 cm² V^-1 s^-1 and polymer solar cells with a highly reproducible power-conversion efficiency of 6%, as well as a thermally stable active layer.
