Light-controlled self-assembly
Triarylamine–fullerene molecules that stack under light into ordered charge channels.
- fibres or spheres, depending on the light source
- separate channels for positive charges and electrons
- very small energy gap (below 1.40 eV), suited to charge transport in both directions
