Abstract

When two oppositely charged self-assembled monolayers of thiolates on gold are laminated???but with their (??) end groups kept apart by just a few angstroms???and then electrically poled, they form a sandwich structure featuring a large, permanent internal dipole. This supramolecular assembly acts as an efficient current rectifier, achieving rectification ratios exceeding 103, switching times on the order of tens of ??s, and undiminished performance over at least 104 seconds of continuous operation under bias.
