Abstract

The present invention relates to the use of copper(I) complexes of the formula Iwhere The present invention further relates to light-emitting layers which comprise at least one copper(I) complex of the formula I, to OLEDs which comprise at least one copper(I) complex of the formula I or an inventive light-emitting layer, and to stationary visual display units which comprise inventive OLEDs.Furthermore, the present invention relates to novel copper(I) complexes of the formula Ia and Ibwhere R, Ar and n are each as defined in formula I, Y in formula Ia is defined as cyano, thiocyanato, alkoxy, aryloxy, alkylthio, arylthio, alkylamino, dialkylamino, arylamino or diarylamino, and Y in formula Ib is defined as halogen, cyano, thiocyanato, alkoxy, aryloxy, alkylthio, arylthio, alkylamino, dialkylamino, arylamino or diarylamino.
