Abstract
The quest for miniaturization of organic nanostructures is fueled by their possible applications in future nanoscale electronic devices. Here we show how a range of nanostructures of reduced dimensionality of the organic semiconductor PTCDA can be realized on Au(111) by intermixing the latter with hydrogen bonding spacer molecules. The purpose of the spacers is to separate nanounits of pure PTCDA, using hydrogen bonds between the anhydride end of PTCDA and amine groups of the spacers. A highly regular array of potential quantum dots can be realized by this approach.
