Claim 1:
2. The polymer of claim 1, wherein the first repeating unit of Formula (I) is a repeating unit of Formula (I-A):, wherein:
R1A, R1B, R1C, R1D, R1E, and R1F are independently aryl or heteroaryl, each optionally substituted with 1, 2, 3, 4, or 5 substituents independently selected from C1-6 alkyl, halo, nitro, cyano, SO3−X+, PO32−X+2, and COO−X+, wherein X+ is H+ or a cation, and provided that at least two of R1A, R1B, R1C, R1D, R1E, and R1F are independently aryl or heteroaryl substituted with 1, 2, 3, 4, or 5 substituents independently selected from SO3−X+, PO32−X+2, and COO−X+, wherein X+ is H+ or a cation;
R2A, R2B, R2C, and R2D are independently H, halo, nitro, cyano, aryl, or heteroaryl;
L1 is an optionally substituted linking heteroatom, arylene, heteroarylene, aralkylene, or heteroaralkylene, wherein said arylene, heteroarylene, aralkylene, and heteroaralkylene are each optionally substituted with 1, 2, 3, or 4 substituents independently selected from C1-6 alkyl, halo, nitro, cyano, aryl, and heteroaryl;
L2 is absent, arylene, or heteroarylene, wherein said arylene and heteroarylene are each optionally substituted with 1, 2, 3, or 4 substituents independently selected from C1-6 alkyl, halo, nitro, cyano, aryl, and heteroaryl; and
L3 is absent, arylene, or heteroarylene, wherein said arylene and heteroarylene are each optionally substituted with 1, 2, 3, or 4 substituents independently selected from C1-6 alkyl, halo, nitro, cyano, aryl, and heteroaryl.
