Single-Molecule Junctions: Nanogap-Independent Conductance Achieved

Revolutionary Discovery in Molecular Electronics

In a groundbreaking advancement for molecular electronics, researchers have discovered that shape-persistent ladder molecules can exhibit a remarkable property: nanogap-independent conductance in single-molecule junctions.

Understanding the Impact

This breakthrough means that these molecules can conduct electricity consistently, regardless of the distance between the electrodes in a molecular junction, a fundamental limitation in conventional molecular junctions.

Key Features of the Discovery

• Ladder-shaped molecules exhibit shape-persistence, maintaining their structure even under external forces.
• The nanogap-independent conductance stems from the unique electronic properties of ladder molecules, enabling efficient charge transport.
