Conductance measurements of polar molecules in a nonconducting solvent
Solution-based single-molecule conductance measurements of α,ω-bis-(carboxylic acids) are conveniently performed using a high-boiling-point nonconducting ethereal solvent. First-principles calculations support experimental observations that linear oligoalkanes exhibit the expected exponential decay...

| Sumario: | Solution-based single-molecule conductance measurements of α,ω-bis-(carboxylic acids) are conveniently performed using a high-boiling-point nonconducting ethereal solvent. First-principles calculations support experimental observations that linear oligoalkanes exhibit the expected exponential decay of conductance with length, whereas junctions comprising cyclic bridge hydrocarbons of different lengths and/or structures exhibit a similar conductance. |
