Molecular potentiometers that can indicate displacement-conductance relationship and predict the molecular con-ductance are of significant importance towards the real application of molecule-based devices but rarely developed so far.To this end,Li et al.design a single-molecule potentiometer based on ortho-pentaphenylene derivatives.They demonstrated that these pseudoelastic molecules can be stretched and compressed by the mechanical force of the Au electrode along with a dramatically variable conductance by up to two orders of magnitude,demon-strating the great potential as angstrom-scale single-molecule po-tentiometers.This work has been published in Nature Communica-tions,2021.
