Charge transport through conjugated azomethine-based single molecules for optoelectronic applications

• The conductance of an azomethine based molecule is determined using the mechanically controlled breakjunction technique.
• A 3-ring azomethine-based molecule has a conductance comparable to its vinyl-based analogue.
• The bulk mobility of azomethine based organic electronics does not appear to be limited by intra-molecular charge transport.

The single-molecule conductance of a 3-ring, conjugated azomethine was studied using the mechanically controlled breakjunction technique. Charge transport properties are found to be comparable to vinyl-based analogues; findings are supported with density functional calculations. The simple preparation and good transport properties make azomethine-based molecules an attractive class for use in polymer and single-molecule organic electronics.
