Exposure of the C-OPV1 self-assembly to high-magnification FESEM conditions causes deformation of the helical fibers. The disappearance of the helicity of some of the fibers in Figure 2 a is a result of this problem. However, a low-magnification image of the densely populated fibers showed uniform left-handed helicity in all fibers.

-4 M at 293 K correspond to the gel state. The contribution from linear dichroism (LD) in the gel state is negligibly small, as turning of the sample had no effect on the type of Cotton effect observed.

The postulated chromophore arrangement in Figure 5 is based on a fluorescence polarization experiment on an OPV gel, which showed packing of the OPV units perpendicular to the fiber axis.
