    • An electroluminescence material comprising one or more polymers which comprise structural units of the formula (I), ##STR1## where the symbols and indices have the following meanings: Ar.sup.1, Ar.sup.2, Ar.sup.3, Ar.sup.4, Ar.sup.5, Ar.sup.6 are identical or different, monocyclic and/or polycyclic aryl and/or heteroaryl groups which may be linked via one or more bridges and/or be condensed and may be unsubstituted or substituted, where Ar.sup.1, Ar.sup.3, Ar.sup.5 and Ar.sup.6 are each divalent and Ar.sup.2 and Ar.sup.4 are each monovalent; R.sup.1 is H, a hydrocarbon radical having from 1 to 22 carbon atoms, which may be unsubstituted or substituted, preferably by F, and can also contain heteroatoms, preferably 0, or Ar.sup.7, where Ar.sup.7 is, independently of Ar.sup.1-6, as defined for Ar.sup.1-6 ; n is 0, 1 or 2. The electroluminescence material of the invention has, inter alia, a low threshold voltage of the electroluminescence and a high efficiency, although the polymers are not conjugated.
    • 包含一种或多种包含式(I),其中符号和指数具有以下含义的结构单元的聚合物的电致发光材料:Ar1,Ar2,Ar3,Ar4,Ar5,Ar6相同或不同 单环和/或多环芳基和/或杂芳基,其可以通过一个或多个桥连接和/或被缩合并且可以是未取代的或取代的,其中Ar 1,Ar 3,Ar 5和Ar 6各自为二价,Ar 2和Ar 4各自为 一价; R 1是H,具有1至22个碳原子的烃基,其可以是未取代的或被F取代的,并且还可以含有杂原子,优选为0或Ar 7,其中Ar 7独立地为Ar1-6,如所定义 对于Ar1-6; n是0,1或2.本发明的电致发光材料尤其具有电致发光的低阈值电压和高效率,尽管聚合物不共轭。
