Claim 0:
1. A polymer (A) comprising:
a structure unit represented by Chemical Formula 1a; and
a structure unit represented by Chemical Formula 1c:, wherein, in the Chemical Formulae 1a and 1c,
M1 is an organic cation, and M2 is an organic anion;
L1 and L2 are the same as or different from each other, and each independently any one group selected from the first group consisting of a linear or branched alkylene group; a divalent saturated hydrocarbon ring group; a divalent aromatic hydrocarbon group; a divalent saturated heteroring group; a divalent aromatic heteroring group; a divalent ring group having at least two rings fused, each ring being selected from a saturated hydrocarbon ring, an aromatic hydrocarbon, a saturated heteroring and an aromatic heteroring; —O—; —C(═O)—; —C(═O)O—; —C(═O)N(R19)-; —N(R19)-; —S—; —S(═O)—; —S(═O)2—; and —S(═O)2O—, or a functional group linking two or more of the groups selected from the first group, and R19 is hydrogen; deuterium; an alkyl group; a saturated hydrocarbon ring group; or an aromatic hydrocarbon group, and two or more R19s are the same as or different from each other;
L1 and L2 are the same as or different from each other, and each independently optionally further substituted with deuterium; a halogen group; a hydroxyl group; an oxo group (═O); or an alkyl group;
n1 is an integer of 0 or greater, and when n1 is 2 or greater, L1s are the same as or different from each other;
n2 is an integer of 0 or greater, and when n2 is 2 or greater, L2s are the same as or different from each other;
Y2, R1, R2 and R3 are each independently any one group selected from the second group consisting of hydrogen; deuterium; a halogen group; a nitrile group; an alkyl group; a saturated hydrocarbon ring group; an aromatic hydrocarbon group; a saturated heteroring group; an aromatic heteroring group; a ring group having at least two rings fused, each ring being selected from a saturated hydrocarbon ring, an aromatic hydrocarbon, a saturated heteroring and an aromatic heteroring; —OR; —OC(═O)R; —C(═O)R; —C(═O)OR; —C(═O)NR2; —NR2; —SR; —S(═O)R; —S(═O)2R; and —S(═O)2OR, or a functional group linking two or more of the groups selected from the second group, and R is hydrogen; deuterium; an alkyl group; a saturated hydrocarbon ring group; an aromatic hydrocarbon group; a saturated heteroring group; an aromatic heteroring group; or a ring group having at least two or more rings fused, each ring being selected from a saturated hydrocarbon ring, an aromatic hydrocarbon, a saturated heteroring and an aromatic heteroring, two or more Rs being the same as or different from each other; and
R1 to R3 and Y2 are the same as or different from each other and each independently optionally further substituted with deuterium; a halogen group; a hydroxyl group;
an oxo group (═O); or an alkyl group,
R4 and R5 are the same as or different from each other, and each independently have the same definition as R1; and
b1 is 0 or 1, b2 is 0 or 1, and a sum of b1 and b2 is 1.
