experiments. Namely, to study the two-electrode nanopore made with molecules
bearing dipolar groups.
Accordingly, the nitroaniline OPE was tested in the nanopore, in the absence
of an orthogonal external electric field, to determine its electronic characteristics.
Then a series of control experiments were first performed with alkanethiol-derived
SAMs and systems containing no molecules. Both the Au-alkanethiolate-Au
junctions and the Au-silicon nitride membrane-Au junctions showed current
levels at the noise limit of the apparatus ( 1 pA) for both bias polarities at

both room and low temperatures. The Au-Au junctions gave ohmic I(V)
characteristics with very low resistances. A device containing a SAM of the
conjugated OPEs but not bearing the nitroaniline functionalities was fabricated
