Abstract
En 中文
Molecular diodes, which enable directional charge transport at the single-molecule scale, are pivotal components for logic operations in molecular electronics, showing promise for future energy-efficient devices and ultracompact circuits. However, achieving high-performance molecular diodes with high rectification ratios (RR), operation stability, and reliable interconnections for logic operations still remains challenging. Recent advancements adopting noncovalent interactions to form supramolecular assemblies demonstrate promise in addressing this challenge by creating asymmetric electronic coupling while preserving efficient charge transport. In this review, we systematically summarize the designs of molecular diodes from single supramolecular junctions to self-assembled monolayer-based supramolecular junctions, and identify strategies using quantum interference to enhance the RR. These approaches provide valuable perspectives for highperformance single-molecule rectifiers through noncovalent supramolecular interactions, showcasing the potential of future bottom-up integration of molecular electronic devices.
