| The continuous miniaturization of electronic devices is accompanying the rapid progress of information technology. Current materials and device architectures, however, are not expected to survive the “shrinking” process as the nanometer scale is approached. Innovative materials and fabrication strategies must be devised for the realization of nanoscaled electronic devices. This need has prompted us to design a chemical strategy for the assembly of electroactive films with tailored properties. We describe here the self-assembly of electroactive multilayers incorporating nanometer-sized bipyridinium bisthiols on gold electrodes. The ability of these films to mediate electron transfer to a redox probe in solution can be regulated by the introduction of electroactive anionic “dopants” in the polycationic bipryidinium layers. These preliminary results suggest the possible design of electrode/multilayer/electrode junctions with current/voltage signatures that can be pre-defined by selecting an appropriate dopant. |
