Donors and Acceptors Made to Order —

from Interlocked Molecules to Supramolecular Materials

The growing needs for miniaturization and better efficiency of electronic devices have inspired enormous interests in obtaining novel semiconductor nanostructures. One particular challenge is to obtain nanostructures with continuous interface between electron donors and acceptors in order to facilitate charge separation and charge transport. This demands the understanding of organization principles of electroactive groups with molecular precision in multi-component systems, which also motivates the design and synthesis of new electron donors and acceptors. Our research focuses on utilizing donor-acceptor interactions to direct the assembly of functional organic nanostructures. Both molecular systems and supramolecular assemblies based on donors and acceptors will be discussed in this talk. I will describe a few examples of the assembly of discrete molecular objects from deliberately designed donor-acceptor systems. Also I will discuss our progress on the development of new donors and acceptors, as well as their organization into ordered supramolecular assemblies. Such assemblies include nanosheets with single-molecular thickness and alternating donor-acceptor stacks. A perspective of the application of supramolecular electronic materials for photovoltaics will also be discussed.
