1. A phenazine polymer comprising:
a plurality of phenazine units; and
a plurality of cross-linking units or both a plurality of co-monomer units and a plurality of cross-linking units,
wherein the individual phenazine units are covalently bonded to a co-monomer unit and/or a cross-linking unit, wherein at least a portion of or all of the individual cross-linking units crosslink three or more units selected from phenazine units and/or co-monomer units, and wherein the number of phenazine units, co-monomer units, and cross-linking units is determined by the following equations:
a1+(b2+x3)→phenazine copolymer  (1)
b+3/2x=a  (2),
b+(n/2)x=a  (10),
wherein 1 is the phenazine units and/or 2 is the co-monomer units and/or 3 is the cross-linking units and/or a is the amount of the phenazine units and/or b is the amount of the co-monomer units and/or x is the amount of the cross-linking units and/or N is the number of reactive sites in the cross-linking unit, and
wherein the phenazine units have the following structure:
