| Outline of Final Research Achievements |
Metal/organic junctions with electrical connections are fundamental “building blocks” in molecular electronics. However, the understanding and property control of metal/organic junctions are underdeveloped because no clear-cut strategy exists for the construction of structured metal/organic junctions. Here, we demonstrate such a strategy for the construction of three-dimensional molecular arrays to a metal electrode by exploiting dendritic molecular architecture. Newly designed dendritic molecules consisting of viologens as the framework and mercapto groups as anchor units form unique self-assembled monolayers (SAMs) on a gold surface. The dendritic molecules exhibit a conical shape and closely pack to form cone arrays on the substrate. Differences in the introduction position of the anchor units result in apical- and basal-type cone arrays in which the spatial concentration of the viologen units can be precisely configured in the molecular cones.
