Self- Assembled Organometallic Molecular Wires for Single Molecule Circuits
The formation and incorporation of 1 D organometallic wires with desirable electronic   ;or magnetic properties into &nbs p;circuits or devices for u se in next generation technologies remains a challe nge.[1] 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 p robing a quasi-1D organometallic coordination complexes in a single molecul e circuit using imidazole linkers activated by pH.[2] We find t hat these structures assemble in situ between two electrodes during junction stretching an d hypothesize that they have an overall spin ½ character. These results identify &nb sp;successful chemical strategies for incorporating molecular and low dimensional materials into next generation e lectronics or energy devices.
