Conductance Properties of Switchable Molecules

Electrochemical Switching of Conductance with Diarylethene-Based Redox-Active Polymers

“…Dithienylethenes have figured prominently in the development of switchable organic electronic devices, especially with regard to photoswitching of conductance, between the nonconjugated open and the conjugated closed forms. ,− Although mostly known as photochemical molecular switches, switching of dithienylethenes can also be achieved electrochemically. − Due to kinetic reasons, redox switching is essentially one way in solution. However, when immobilized on electrodes, both ring-opening and ring closing can be achieved electrochemically. ,− The difference in redox potentials between the open and closed states can potentially allow this class of molecular switches to function as active components in organic electronic devices, particularly in terms of switching of conductance.…”
