Figure shows the proposed BQ redox reaction cycle that mediates transient colloidal crystal dynamics. In the context of fuel driven dissipative assembly we are interested in identifying the 'chemical fuel,' the forward and backward reactions that drive transient behavior, and demonstrating the key differences between the present system and prior works. The BQ was reduced to quinone dianions at the cathode, which have a high pKa of ~11 and rapidly consume protons, increasing the solution pH. The release of hydroxyl ions from water ionization triggered the repulsive EO flow that separates the colloids. In this context, BQ can be considered a pre-fuel molecule and hydroxyl ions the chemical fuel that activates the colloidal crystal dynamics.
