Abstract:
1. A low molecular weight or polymeric organic electroluminescent or laser material for use in electronic applications selected from the group consisting of A) a homo- or copolymer based on polyspiro, B) a low molecular weight compound having a 3-dimensional spirobifluorene structure, C) a low molecular weight compound having a 3-dimensional triptycene structure, and D) a derivative of quinacridone R is a straight-chain, branched or cyclic alkyl, alkoxyalkyl, alkoxy, thioalkoxy group having from 1 to 20 carbon atoms, C Z is —O—, —S—, —CO—, —COO—, —O—CO— or a bivalent group —(CR X is —O— or a bivalent group —(CR n is an integer from 1 to 20, with the proviso that the number of these A groups is limited by the maximum number of available substitutable hydrogen atoms.
