In September 2024, Nijhuis’s group and Yuan Li’s group explored the performance of bisferrocenyl-based molecular diodes, specifically focusing on the impact of molecular length, electrode type, and assembly effects on rectification behavior. By systematically varying these parameters, the authors achieved high rectification ratios (R) exceeding the "Landauer limit" across a range of molecular lengths and metal substrates. This work provides insights into optimizing self-assembled monolayer (SAM) junctions for robust, high-performance molecular diodes, offering significant potential for molecular electronics.
