1. A polymer, comprising a first repeating unit of Formula (I):, , and
a second repeating unit of Formula (II):, 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;
R1G and R1H are independently H, aryl, or heteroaryl, wherein said aryl and heteroaryl are 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;
R3A, R3B, R3C, R3D, R3E, and R3F are independently aryl or heteroaryl, each optionally substituted with 1, 2, 3, 4, or 5 substituents independently selected from C1-6 alkyl; halo, nitro, and cyano;
R3G and R3H are independently H, aryl, or heteroaryl, wherein said aryl and heteroaryl are each optionally substituted with 1, 2, 3, 4, or 5 substituents independently selected from C1-6 alkyl, halo, nitro, and cyano;
A1 and B1 are independently arylene, heteroarylene, aralkylene, or heteroaralkylene, each optionally substituted with 1, 2, 3, or 4 substituents independently selected from halo, nitro, cyano, aryl, and heteroaryl;
A2 and B2 are independently absent, arylene, or heteroarylene, wherein said arylene and heteroarylene are each optionally substituted with 1, 2, 3, or 4 substituents independently selected from halo, nitro, cyano, aryl, and heteroaryl;
L1 and K1 are independently 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 and K2 are independently 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 and K3 are independently 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;
provided that the repeating unit of Formula (I) is not,
