Aryl-substituted poly (p-arylene-vinylenes), process for their preparation and their use in electroluminescence components

摘要

Poly(p-arylene-vinylenes) comprising repeating units of the formula (I), ;where the symbols and indices have the following meanings:;Y¹, Y², Y³: identical or different, CH, N;;Aryl: an aryl group having from 4 to 14 carbon atoms;;R, R: identical or different, each a straight-chain or branched or cyclic alkyl or alkoxy group having from 1 to 20 carbon atoms, where one or more non-adjacent CH₂ groups may be replaced by O, S, CO, COO, OCO, NR¹, (NR²R³)^{A, or CONR4 and one or more H atoms may be replaced by F, or else CN, F, Cl or an aryl group having from 4 to 14 carbon atoms which may be substituted by one or more nonaromatic radicals R;;R1, R2, R3, R4: identical or different, aliphatic or aromatic hydrocarbon radicals having from 1 to 20 carbon atoms or else H;;A: a singly charged anion or its equivalent;;m: 0, 1 or 2;;n: 1, 2, 3, 4 or 5;;are suitable as electroluminescence materials.}
