The measured conductance plotted against the calculated molecular length comparison between alkane rings and alkane chains.

Caption

The blue star signs of saturated alkane rings show exponentially decay conductance and the decay trend is similar to saturated alkane chains, which is presented by orange squares. The alkane rings are more insulating than alkane chains when compare the identical molecular length.
