Masha KamenetskaSelf-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.[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 probing a quasi-1D organometallic coordination complexes in a single molecule  circuit using  imidazole linkers activated by pH.[2] 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.
