dc.description.abstract | This Communication describes polarity inversion in molecular rectification and the related mechanism. Using a supramolecular engineered, ultrastable, binary-mixed self-assembled monolayer (SAM) composed of an organic molecular diode (SC11BIPY) and an inert reinforcement molecule (SC8), we probed a rectification ratio (r)-voltage relationship over an unprecedentedly wide voltage range (up to vertical bar 3.5 V vertical bar) with statistical significance. We observed positive polarity in rectification at vertical bar 1.0 V vertical bar (r = 107), followed by disappearance of rectification at similar to vertical bar 2.25 V vertical bar, and then eventual emergence of new rectification with the opposite polarity at similar to vertical bar 3.5 V vertical bar (r = 0.006; 1/r = 162). The polarity inversion occurred with a span over 4 orders of magnitude in r. Low-temperature experiments, electronic structure analysis, and theoretical calculations revealed that the unusually wide voltage range permits access to molecular orbital energy levels that are inaccessible in the traditional narrow voltage regime, inducing the unprecedented in situ inversion of polarity. | - |
