Description
Summary:The recently discovered "rods-in-belt" supramolecular complexes with AuCu or AuAg cluster cores exhibit self-assembly behavior, have a very unusual structural motif, and what is most important, show remarkable light emitting properties. The electronic and photophysical characteristics of these unique objects can be relatively easy tuned by modifying the ligand (alkynyl and phosphine) environment. Because of these properties the "rods-in-belt" supramolecules could serve as building blocks for next generation electronics, and in particular, for light-emitting devices and in bioimaging applications.
