Fe(acac)3 has been used as the catalyst in cross-coupling reactions of aryl Grignard reagents with 1,4-bis(2- bromovinyl)benzenes affording bis(2-arylvinyl)benzenes. Effects of alkoxy substituents on both reactants and of the temperature on the reaction outcome are investigated.

The present invention relates to an electro-optical device containing a) an anode, b) a cathode and c) at least one first emitter layer arranged between anode and cathode, containing at least one semiconducting, organic material, said device being characterized in that at least one second emitter layer comprising at least one polymer having hole-conducting properties and at least one emitter is arranged between the first emitter layer and the anode, and to the use thereof. The use of two emitter layers allows simple production from solution, and the production of electroluminescence devices having broadband emission.
