In this study, we synthesized a threefold symmetric disc-shaped TTF derivative with chirality at the molecular end. This molecule forms a CT complex when mixed with the acceptor molecule F₄TCNQ, and it was revealed that a one-dimensional helical assembly can be obtained by dropping a DMSO solution of this complex onto a mica substrate. The electrical conductivity of this assembly in the bulk state was 2.3 × 10^-3 S/cm, and it exhibited semiconducting behavior. The maximum induced electromotive force was 1.34 mV.
