Molecular Structure–Function Relations of the Optical Properties and Dimensions of Gold Nanoparticle Assemblies


  • This research was supported by the Helen and Martin Kimmel Center for Molecular Design and by the Minerva Foundation. The transmission electron microscopy studies were conducted at the Irving and Cherna Moskowitz Center for Nano and Bio-Nano Imaging at the Weizmann Institute of Science.

Stolen identity: The molecular geometries of a series of cross-linkers that bear between one and four pyridyl moieties are expressed in the optical properties of AuNP assemblies (see picture). TEM analysis indicates that the molecular-level structural differences of the cross-linkers are also transferred at the submicrometer level in the formation of the AuNP assemblies.
