1. An electrically-degradable polymer moiety comprisinga quinone compound of the formula:

  • wherein R1, R2, R3, R4, R5, and R6 are selected from the group comprising hydrogen, alkyl, aryl, alcohol, ether, thiol, thioether, amine, cyano, halo, nitro, ketone, aldehyde, ester, amide, thioester, carbonate, carbamate, and urea, X and Y can be the same or different and are selected from the group comprising vinyl sulfone, epoxide, alkyl halide, alkene, amine, alcohol, acid halide, acid anhydride, sulfate, phosphate, isocyanate, isothiocyanate, and thiol alkyl groups, wherein at least one of X and Y is capable of degradation upon reduction of the quinone, such that the polymer moiety is capable of degrading upon exposure to a change in electric potential.
