We have discovered molecular circuit elements that resolve decade long challenges in organic electronics. Our devices are robust, reliable, uniform and we have developed a deterministic understanding of their molecular redox mechanisms. The films are compatible with existing circuit fabrication protocols. In addition, via molecular engineering routes, we are able to achieve unprecedented characteristic tunability in voltage, current, number of states and also in the mode of operation. These elements can function both as non-volatile memory for in-memory computing and also, on the edge of chaos depending on how they are operated.
