1. A polymer having at least one repeat unit of the following formula (I):

OG Complex Work Unit Chemistry
wherein
X is selected from O, S, NR or CR2;
Ar1, Ar2, Ar3 and Ar4 are the same or different at each instance and are independently a mono- or polycyclic, aromatic or heteroaromatic ring system which has 5 to 60 aromatic ring atoms and optionally substituted by one R radical;
a and b are the same at each instance and are 1; where (a+b)=2;
c and d are the same at each instance and are 1;
e and f are the same at each instance and are independently 0, 1, 2 or 3;
R is the same at each instance and is independently H, D, F, Cl, Br, I, N(R1)2, CN, NO2, Si(R1)3, B(OR1)2, C(═O)R1, P(═O)(R1)2, S(═O)R1, S(═O)2R1, OSO2R1, a straight-chain alkyl, alkoxy or thioalkoxy group having 1 to 40 carbon atoms, an alkenyl or alkynyl group having 2 to 40 carbon atoms or a branched or cyclic alkyl, alkoxy or thioalkoxy group having 3 to 40 carbon atoms, each of which optionally substituted by one or more R1 radicals, where one or more nonadjacent CH2 groups optionally replaced by R1C═CR1, C≡C, Si(R1)2, C═O, C═S, C═NR1, P(═O)R1, SO, SO2, NR1, O, S or CONR1 and where one or more hydrogen atoms optionally replaced by D, F, Cl, Br, I or CN, or a mono- or polycyclic, aromatic or heteroaromatic ring system which has 5 to 60 aromatic ring atoms and optionally substituted in each case by one or more R1 radicals, or an aryloxy or heteroaryloxy group which has 5 to 60 aromatic ring atoms and optionally substituted by one or more R1 radicals, or an aralkyl or heteroaralkyl group which has 5 to 60 aromatic ring atoms and optionally substituted by one or more R1 radicals, or a diarylamino group, diheteroarylamino group or arylheteroarylamino group which has 10 to 40 aromatic ring atoms and optionally substituted by one or more R1 radicals; or a crosslinkable group Q, where two or more R radicals together optionally form a mono- or polycyclic, aliphatic, aromatic or heteroaromatic ring system;
is the same at each instance and is independently H, D, F or an aliphatic hydrocarbyl radical having 1 to 20 carbon atoms, an aromatic or a heteroaromatic hydrocarbyl radical having 5 to 20 carbon atoms, in which one or more hydrogen atoms optionally be replaced by F; where two or more R1 substituents together optionally form a mono- or polycyclic, aliphatic, aromatic or heteroaromatic ring system; and the dotted lines represent bonds to adjacent repeat units in the polymer,
and wherein the polymer contains from 5 to 75 mol %, based on 100 mol % of all copolymerizable monomers present as repeat units in the polymer, of the at least one repeat unit of the formula (I).
