摘要： The invention concerns the use, as electroluminescent materials, of polymers containing structural units of general formula (I) -[A?1-(A2)C=CH-A3-CH=C(A2¿)]-, wherein A?1, A2 and A3¿, which are identical or different, designate mono and/or polynuclear aryl and/or heteroaryl groups which are optionally linked via one or a plurality of bridges, and preferably via one bridge, and/or are condensed and can be optionally substituted, and wherein A?1 and A3¿ each have two bonds and A2 has one bond. The polymers of formula (I) according to the invention are distinguished above all by their high degree of stability at high fluorescence quantum yields.
