Self-Assembled Organometallic Molecular Wires for Single Molecule Circuits
The formation and incorporation of 1D organometallic wires&nb sp;with desirable electronic or magnetic& nbsp; properties into circuits or devices for use in & nbsp;next generation technologies remains a challenge.[1] Here, I will desc ribe the design rules that my group has identified for forming robust molec ular wire junctions that contain transition metal atoms. I will then demons trate a strategy for assembling and electrically probing a quasi-1D organom etallic coordination complexes in a single molecule circuit using &nb sp;imidazole linkers activated by pH.[2] We find that these structure s assemble in situ between two electrod es during junction stretching and hypothesize   ;that they have an overall spin ½   ;character. These results identify successful chemi cal strategies for incorporating molecular an d low dimensional materials into next generation electronics or energy devi ces.
