Fine-tuning organic circuits: Monolayer terminal groups and molecular junctions

Self-assembled monolayers are organic molecules that spontaneously coordinate to a metal surface. If this metal surface is an electrode, then a current can pass through the organic monolayer and interact with a second electrode on the terminal side of the molecule. This current can be controlled by changing the characteristics of the organic molecule, such as making it longer or adding polar substituents or other functional groups. This tailoring of organic circuits is part of a bigger project of creating organic-based electronics.

The story is too old to be commented.
