Fig. 7: Transmission pathways of o-PP derivatives in different conformers.

a Transmission pathways for the AA and AB conformers of o-PP-2SMe. b Transmission pathways for the AA and AB conformers of o-PP-2CN. The blue arrows represent charge transport from the source electrode to the drain electrode, and the red ones represent the transport in the opposite direction; the larger size of arrows also indicates the higher possibility of charge transport.
