Abstract Translated from German Konjugierte Polymere, enthaltend Wiederholeinheiten der Formel (I), <IMAGE> A, B, C, D: sind gleich oder verschieden jeweils eine bis fünfzehn gleiche oder verschiedene Arylen- und/oder Heteroarylen- und/oder Vinylengruppen, die, wie auch das Spirobifluorengerüst, gegebenenfalls substituiert sein können; S: ist gleich oder verschieden ein Substituent; m, n: sind 0 oder 1. Die erfindungsgemäßen Polymere der Formel (I) eignen sich als Elektrolumineszenzmaterialien und zeichnen sich insbesondere durch eine hohe Farbeinheit der Emission aus. <IMAGE> Conjugated polymers containing repeating units of the formula (I), <IMAGE> A, B, C, D: are identical or different, each one to fifteen identical or different arylene and / or heteroarylene and / or vinylene groups, which, like that Spirobifluorene skeleton, which may be substituted; S: the same or different is a substituent; m, n: are 0 or 1.
