Amine Linked Single Molecule Circuits: Systematic Measurements & Understanding
02 Jul 2007 | Online Presentations | Contributor(s): Mark S Hybertsen
Formation and function of well-defined linkages between organic molecules and metallic electrodes has been a key issue in the field of molecular electronics. We recently discovered that the conductance of single molecule junctions formed using gold-amine linkages can be measured reliably and reproducibly. The conductance of approxi-mately 40 different amine linked molecules from several families has been measured revealing systematic trends with length, conformation, conjugation and substituent. In this talk, I will present results of the experiments performed at the Columbia NSEC together with our present theoretical understanding of the properties and function of the gold-amine link in single molecule conductance.
