Structures of OPV3-based molecules and MCBJ setup. (a) Structures of OPV3-based molecules studied in this work. The para- (blue) and meta- (red) coupled benzene rings are connected to acetyl-protected thiols (green) by vinyl spacers (black). (b) Scheme of the mechanically controlled break-junction (MCBJ) setup. Inset, false-color scanning electron micrograph of a MCBJ device.
