Abstract

original image

A C60-capped poly(3-hexylthiophene) dyad molecule (PCB–P3HT) serves as a “surfactant” to enhance the solubility of fullerenes in poor solvents such as tetrahydrofuran, a selective good solvent for P3HT. Moreover, the phase separation of PCB–P3HT in thin films leads to well-defined nanostructures wherein the solvent plays a vital role in determining the morphology and the structure of these self-assembling structures.
