“We found that the well-arranged edge-on PM6 chains can be twisted into face-on orientation by the dipole–dipole interaction with L8-ThCl, and refined into nanofibrils with enhanced and denser π−π stacks,” the scientists explain in the paper. “Meanwhile, the good miscibility and intermolecular interactions between L8-BO and L8-ThCl in W and S-shaped packed dimers can effectively strengthen and regulate the packing networks of acceptors into one-dimension fibrils with high crystallinity.”
damn, it seems obvious when they lay it out like that.
