ARYL-SUBSTITUTED POLY(P-ARYLENE VINYLENES), METHOD FOR THE PRODUCTION AND USE THEREOF IN ELECTROLUMINESCENT COMPONENTS

摘要

The invention relates to poly(p-arylene vinylenes), containing repeating unit of formula (I), wherein the symbols and indices have the following meanings; Y1, Y2, Y3 are the same or different and means CH, N; aryl stands for an aryl group with 14 C atoms; R', R'' are the same or different and mean a straightchained, branched or cyclic alkyl or alkoxy group with 1 to 20 atoms, wherein one or several non-adjacent CH2 groups can be substituted by -O-, -S-, -CO-, COO-, -O-CO-, -NR1, -(NR2R3)+-A-, or -CONR4-, and wherein one or several H atoms can be substituted by F; R', R'' are CN, F, Cl or an aryl group with 4 to 14 C atoms, which can be substituted by one or several nonaromatic radicals R', R1, R2, R3, R4 are the same or different and mean aliphatic or aromatic hydrocarbon radicals with 1 to 20 C atoms or also H. A- is a single charged anion or the equivalent thereof; m means 0, 1 or 2; n stands for 1, 2, 3, 4 or 5. Said substances are suitable as electroluminescent materials.
