pH-activated single molecule conduction and imidazole binding mechanism on gold


Abstract image

We isolate imidazole as a pH-activated bond, a stable single molecule – to form gold bonds, with several distinct configurations and repetitive electrical characteristics. Using the technique of scanning the microscope break point (STMBJ) of the scan tunnel, we find the multiple conduction signature in integers 1.9 10–2G0 And 1.2. 10–4G0 And to determine that this molecule bridges electrodes in its teratonic form through nitrogen atoms only under basic conditions, several molecules can be connected in parallel and in series. The length of these jungles can be extended to the length of the molecule, suggesting that the plastic deformation of the gold electrodes occurs during stretching. Computational theory of density theory has shown that bonds with imidazolate show a bond strength of bond2 eV, which can lead to the plastic extraction of gold atoms. Based on these results, we believe that the lower conductance peaks correspond to the repetitive chains of molecular-gold units that we form and measure on the ground.
