Rapid electron propagation through molecular wire monolayers sandwiched between two gold electrodes

Conjugated bisthioester 1 was synthesized applying Sonogashira coupling reactions. Using self-assembly in combination with nanoparticles deposition techniques, we developed a novel method to fabricate a "gold electrode-molecular wire monolayers-gold nanoparticles" sandwich-like structure. Rapid electron propagation through this sandwich-like structure was observed by cyclic voltammetry and ac impedance measurements.
