Abstract
The electronic properties of supramolecular materials, such as charge transfer and separation efficiency, depend upon the molecular arrangement of the single components and their mutual interactions. These features determine the effectiveness of crucial properties of the final material such as electroluminescence and photoconversion. A crucial point, however, is how to rationally control the molecular structure in order to attain powerful electronic communication at different length scales from the molecule to the material. Molecular constituents, in fact, generally interact only weakly and randomly, and, moreover, the final molecular arrangement is difficult to predict when molecular components with different characteristics are mixed together. EMBRACE aims at controlling the structural arrangement of molecular components with distinct electronic properties for the formation of P-N heterojunctions in the aggregate state. The main goal of EMBRACE is the application of the design principles to the development of nanostructured materials with improved and tailored electronic communication properties. To achieve these results EMBRACE exploits the principles of molecular recognition to enforce social self-assembly of donor- (D) and acceptor-type (A) π-systems at different length scales, from molecular to bulk. We envision that the preorganization of the opposite type semiconductors in dyads in solution will provide new (nano)materials with unprecedented control over the final morphologies and will give access to the rational design of novel supramolecular architectures. In turns, we expect that this will impact the efficiency of formation of a charge-transfer state (CTS) and the performances of charge separation at the interface
