Abstract

The fabrication of a gold\polymer/gold nanojunction by the self-assembly of a rigid polymer, namely poly(p-phenyleneethynylene)s with thioacetyl groups, between gold nanogap electrodes was discussed. It was shown that the self-assembly depends on the ideal rigidity of the polymer molecules and the strong affinity of the thioacetyl/thiol end groups of the polymer for the Au surface. The current-voltage (I-V) characteristics of the conjugated polymer nanojunction exhibited stepwise features at room temperature. The polymer nanojunctions can be self-assembled by Au nanogap electrodes because of the ideal rigidity and connectivity of the polymer molecules.
