In particular, we have theoretically explored the possibility to chemically functionalize a carboxylate–Cu(110) system to specifically tune its electronic structure. Experimentally, it could be proven that the transport properties of the carboxylate–Cu(110) interface indeed revealed specific features in the d<alternatives><inline-graphic mimetype="image" xlink:href="ark:/27927/pgg3v1brn2z" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /><mml:math altimg="urn:x-wiley:15213951:media:pssb201349076:pssb201349076-math-0001" display="inline" overflow="scroll" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi>I</mml:mi><mml:mo>/</mml:mo><mml:mi mathvariant="normal">d</mml:mi><mml:mi>V</mml:mi></mml:math></alternatives> spectra corresponding to the used functionalization process.

Furthermore, transport calculations for molecules with different anchoring groups between two Cu(110) electrodes are also discussed. <inline-graphic xlink:href="ark:/27927/pgg3v1bmqh7" content-type="pssb201349076-gra-0001" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> <p>Schematic view of a STM tip probing a carboxylate molecule chemisorbed on the Cu(110) surface with the corresponding energy level alignment in the case of a zero bias voltage.</p> </sec> </abstract>
