Self-Assembled Organometallic Molecular Wires for Single Molecule Circuits
The formation and incorporation of 1D organometallic wires with desirable electronic or magnetic properties into circuits or devices for use in next generation technologies remains a challenge. Here, I will describe the design rules that my group has identified for forming robust molecular wire junctions that contain transition metal atoms. I will then demonstrate a strategy for assembling and electrically probing a quasi-1D organometallic coordination complexes in a single molecule circuit using imidazole linkers activated by pH. We find that these structures assemble in situ between two electrodes during junction stretching and hypothesize that they have an overall spin ½ character. These results identify successful chemical strategies for incorporating molecular and low dimensional materials into next generation electronics or energy devices.
