Abstract:
1. A polymer, characterized in that it comprises at least 1 mol % of units of the formula (I), where the symbols and indices used have the following meanings: X is identical or different on each occurrence and is in each case C(R3)(R4) or N(R3); Z is identical or different on each occurrence and is in each case C(R5) or N; R1, R2, R3, R4 are identical or different on each occurrence and are in each case fluorine, chlorine, bromine, iodine, CN, N(R6) R5 is identical or different on each occurrence and is in each case H, F, CN, N(R6) R6 is identical or different on each occurrence and is in each case H, a straight-chain, branched or cyclic alkyl chain having from 1 to 22 carbon atoms in which one or more nonadjacent carbon atoms may also be replaced by O, S, CO—O, O—CO—O, where one or more H atoms may also be replaced by fluorine, an aryl group having from 5 to 40 carbon atoms in which one or more carbon atoms may also be replaced by O, S or N and which may also be substituted by one or more nonaromatic radicals R6; a is identical or different on each occurrence and is in each case 0 or 1; b is identical or different on each occurrence and is in each case 1 or 2; with the proviso that poly(arylene-vinylene) compounds in which one arylene unit is a 9,10-dialkyl-9,10-dihydrophenanthrene are excluded from the invention; and the bond shown as a broken line indicates the linkage in the polymer.
