Abstract
The present invention describes poly(arylenevinylenes) comprising poly(arylphenylenevinylene) units whose phenylene unit bears a further aryl substituent in the para or meta position relative to the first aryl radical (formula (I)), as a result of which the operating life in EL elements can be increased and high EL efficiencies can be maintained.
