Right here we report molecular junctions primarily based on molecular switches that toggle stably and reliably between a number of operations to reconfigure digital gadgets at molecular size scales. Moderately than static on/off switches that at all times revert to the identical state, our voltage-driven molecular gadget dynamically switches between excessive and low conduction states throughout six consecutive proton-coupled electron switch steps. By altering the utilized voltage, totally different states are accessed leading to in-operando reconfigurable digital functionalities of variable resistor, diode, reminiscence, and NDR (unfavorable differential conductance). The switching conduct is voltage pushed but in addition has time-dependent options making it potential to entry totally different reminiscence states. This multi-functional change represents molecular scale {hardware} operable in solid-state gadgets (within the type of electrode—monolayer—electrode junctions) which might be attention-grabbing for areas of analysis the place you will need to have entry to time-dependent modifications resembling brain-inspired (or neuromorphic) electronics.
