The proposal aims at exploring charge transport in metal (carbon)/molecule/metal (carbon) junctions employing a nanoscale electrochemical approach. Based on the concept of “electrolyte gating” single molecule and ensemble measurements on electron transport in active nanometer-scale junctions will be combined with structure-sensitive in-situ techniques (STM/STS, current-probe AFM (CP-AFM), infrared (SEIRAS) and gap-mode Raman spectroscopy (SHINERS)). We attempt to establish an electrochemical surface-science-based approach at the nanoscale with a particular focus on contact, molecular backbone and functionality. We will apply the following topology: A central functional unit F is attached via spacer units S and anchoring groups A, either symmetrically (A-S-F-S-A) or asymmetrically (A-S-F-S) to contacting leads. The latter are represented either by the tip of an STM or CP-AFM and an adsorbate-modified single crystal metal substrate or a pair of nanoelectrodes in a fixed or variable (mechanically-controlled break junction, MCBJ) geometry. Functional moieties will be placed either within the molecular backbone or as pendent substituents. We aim at evaluating how charge transport through single molecules and hybrid assemblies is modulated by external stimuli. We will explore switching phenomena via electric field control, redox control and with light-responsive molecules. We aim at establishing fundamental aspects of electron transport as well as relationships between structural functionality of nanoscale molecular junctions and their electronic response upon electrochemical and/or light stimulation at the single molecule level. The development and implementation of CP-AFM and gap-mode Raman spectroscopy (in combination with our MCBJ set-up) for applications in a nanoscale electrochemical environment will enable (1) unprecedented load control and (2) direct access for monitoring structure changes upon stimulations. Application studies towards molecular recognition are anticipated.We identify the following specific working packages:WP 1:Search for alternative contact conceptsWP 2:Electron transport in “inactive” molecular wires.WP 3:Stimulus-responsive electron transport in “active” nanojunctionsWP 4:Electrochemical MCBJ combined with gap-mode Raman spectroscopyWP 5:Load control and recognition in electrochemical CP-AFMThe project will provide unique new insights into fundamental structure-property relationships in electrochemical nanojunctions and their response upon stimulation. New grafting concepts will be developed. Exciting new results on nanoscale structure and reactivity are expected from the development and application of in-situ single molecule Raman spectroscopy and CP-AFM. The proposed research represents an interdisciplinary approach, which will benefit substantially from several active collaborations with complementary teams representing expertise in molecular and supramolecular chemistry (M. Bryce, Durham; S. Decurtins, Bern; N. Martin, Madrid; M. Mayor, Basel; K. Müllen, Mainz; R. Royal/Ch. Bucher, Grenoble), surface science (R. Fasel, EMPA), interfacial spectroscopy (Z. Q. Tian, Xiamen), theoretical physics (C. Lambert, Lancaster; F. Pauly, Karlsruhe), and engineering (Samlab, EPFL).
