Abstract

Ordered poly(arylene-vinylene)terpolymers, process for their preparation and their use as electroluminescence materials Poly(arylene-vinylene) terpolymers comprising repeating units of the formula (I), ##STR1## where the symbols have the following meanings: PA0 Ar.sup.1, Ar.sup.2, Ar.sup.3 are identical or different and are monocyclic or polycyclic, substituted or unsubstituted aryl or heteroaryl groups which may be linked via one or more bridges or be fused, PA0 R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8 are identical or different and are each H or a hydrocarbon radical having from 1 to 22 carbon atoms which may be substituted, preferably by F, and may also contain heteroatoms, preferably O, are suitable as electroluminescence materials.
