Phenazine copolymers and uses thereof

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:
• wherein n is 0 to 100 and X1 is chosen from a co-monomer unit, a cross-linking unit, and —H;
• wherein R1, R2, R3, R4 are independently at each occurrence chosen from —F, —Cl, —Br, —I, and —CH═O and X2 is chosen from a co-monomer unit, a cross-linking unit, and —H;
• wherein R5, R6, R7, R8 are independently at each occurrence chosen from —F, —Cl, —Br, —I, and —CH═O and X3 is chosen from a co-monomer unit, a cross-linking unit, and —H;
• or a combination thereof.
