Molecular electronics

Molecular electronics is the use of molecules as the primary building block for electronic circuitry. A molecular approach, it is hoped, will enable the construction of much smaller circuits than is currently possible using the more conventional semiconductors such as silicon. The motion of the electrons in such devices is inherently governed by quantum mechanics.

    Organometallic frameworks have raised considerable interest in the area of nanoelectronics, but they are usually prepared at the ensemble level resulting in limited control. Vladyka et al. control the formation of single oligomer chains, unit by unit, in a mechanically controllable break-junction setup.

    Electron transport chains rely on interactions between redox proteins, but the distance-dependence of the electron transfer rate through the solution is unknown. Here, the authors show that the current between two redox protein partners occurs at long distances and is electrochemically gated.

    Despite recent advances in organic optoelectronics development, integration of electronics and photonics in a chip remains a challenge. Here, the authors demonstrate organic field-effect optical waveguides that control propagating photons by the electric field produced in an organic transistor.
