Various embodiments disclosed relate to conjugated polyelectrolytes and methods of using the same. Various embodiments provide a conjugated polyelectrolyte including a subunit having the structure —R1—Y—R2—Z—. At each occurrence, R1 is independently chosen from 1,4-bonded phenylene substituted by —X—R3—R4 j times and 2,5-bonded thiophene substituted by —X—R3—R4 j times. At each occurrence, Y is independently chosen from a bond and —C≡C—. At each occurrence, R2 is independently chosen from a bond, a substituted or unsubstituted phenylene, thiophenylene, azulenylene, heptalenylene, biphenylene, indacenylene, fluorenylene, phenanthrenylene, triphenylenylene, pyrenylene, naphthacenylene, chrysenylene, biphenylenylene, anthracenylene, and naphthylene. At each occurrence, Z is independently chosen from a bond and —C≡C—. The variables j, R3, and R4 are as defined herein. |

1. A conjugated polyelectrolyte comprising a subunit having the following structure:
|R1—Y—R2—Z|, wherein
at each occurrence, R1 is independently chosen from: at each occurrence, j is independently chosen from 0, 1, 2, 3, and 4,at each occurrence, X is a bond, —O—, —NH—, or —S—,at each occurrence, R3 is a (C1-C20)hydrocarbylene interrupted by 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9 heteroatoms,at each occurrence, R4 is independently chosen from —H, —R5, -(1,4-substituted 1,4-diazabicyclo[2.2.2]octane-1,4-diium)-R5, 3-R5-substituted imidazolium, pyridinium, —SO3−, —CO2H, —CO2−, —N+(R5)3, and —N(R5)2,at each occurrence, R5 is independently chosen from a substituted or unsubstituted (C1-C10)hydrocarbyl,at each occurrence, Y is independently chosen from a bond and —C≡C—,at each occurrence, R2 is independently chosen from a bond, a substituted or unsubstituted phenylene, thiophenylene, azulenylene, heptalenylene, biphenylene, indacenylene, fluorenylene, phenanthrenylene, triphenylenylene, pyrenylene, naphthacenylene, chrysenylene, biphenylenylene, anthracenylene, and naphthylene, andat each occurrence, Z is independently chosen from a bond and —C≡C—. |
