摘要

A novel oligo-p-phenylene-unit-containing polymer containing at least one structural element of the general formula (AkB)n in which the symbols and indices have the following meanings: A is the same as or different from (a), B is the same as or different from (b), Y is the same as or different from (E)-CR<9>=CR<10>, -CC- or -CHR<11>-CHR<12>; R<1>, R<2>, R<3>, R<4>, R<5>, R<6>, R<7>, R<8>, R<9>, R<10>, R<11>, R<12> are mutually independently the same or different in the individual structural elements, H is a straight-chained or branched alkyl chain with 1 to 22 C atoms, in which one or more non-adjacent CH2 groups may also be substituted by -O-, -S-, -SO2-, -COOC-, -OOC- and/or phenylene, aryl or aryloxy groups, in which the aromatic in said groups may be substituted by C1-C22 alkyl, C1-C22 alkoxy, Br, Cl, F and/or CN, Br, Cl, F, CN or alkoxycarbonyl with 2 to 23 atoms, k is 1 to 25 and n is 1 to 200, is suitable for use as electroluminescent material.
