I will report our recent work in understanding and controlling adaptive charge-transport behaviors in reconfigurable molecular networks of polycyclic aromatic hydrocarbons in non-aqueous electrolytes.  This will include a detailed look into their network forming ability as a function of concentration, temperature, and imposed state of charge. Their application as embedded 3-D redox mediators will be discussed in the context of a hybrid Li-S redox flow battery. The design of our network-forming redox mediators was informed by a new high throughput computational platform developed by our team, where we can selectively amplify or dampen electronic charge transport at specific stages in a charge or discharge sequence.
