Claim:
1. A copolymer comprising: a first unit of Formula 1; and a second unit of Formula 2: wherein in Formulae 1 and 2: l is a real number, which is 0<l<1 as a mole fraction, m is a real number, which is 0<m<1 as a mole fraction, and l+m=1; A and B are different from each other, and comprise one or more moieties selected from the group consisting of a direct bond; a monocyclic or polycyclic substituted or unsubstituted divalent heterocyclic group; a monocyclic or polycyclic substituted or unsubstituted divalent aromatic cyclic group; and a fused divalent ring in which a monocyclic or polycyclic heterocyclic group and a monocyclic or polycyclic aromatic cyclic group are substituted or unsubstituted; R1, R4, R5 and R8 are the same as or different from each other, and are each independently selected from the group consisting of hydrogen; deuterium; a halogen group; a nitrile group; a nitro group; an imide group; an amide group; a hydroxyl group; a substituted or unsubstituted alkyl group; a substituted or unsubstituted cycloalkyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted aryloxy group; a substituted or unsubstituted alkylthioxy group; a substituted or unsubstituted arylthioxy group; a substituted or unsubstituted alkylsulfoxy group; a substituted or unsubstituted arylsulfoxy group; a substituted or unsubstituted alkenyl group; a substituted or unsubstituted silyl group; a substituted or unsubstituted boron group; a substituted or unsubstituted alkylamine group; a substituted or unsubstituted aralkylamine group; a substituted or unsubstituted arylamine group; a substituted or unsubstituted heteroarylamine group; a substituted or unsubstituted aryl group; and a substituted or unsubstituted heterocyclic group; and R2, R3, R6 and R7 are the same as or different from each other, and are each independently selected from the group consisting of hydrogen; deuterium; a halogen group; a nitrile group; a nitro group; an imide group; an amide group; a hydroxyl group; a substituted or unsubstituted cycloalkyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted aryloxy group; a substituted or unsubstituted alkylthioxy group; a substituted or unsubstituted arylthioxy group; a substituted or unsubstituted alkylsulfoxy group; a substituted or unsubstituted arylsulfoxy group; a substituted or unsubstituted alkenyl group; a substituted or unsubstituted silyl group; a substituted or unsubstituted boron group; a substituted or unsubstituted alkylamine group; a substituted or unsubstituted aralkylamine group; a substituted or unsubstituted arylamine group; and a substituted or unsubstituted aryl group.
