This invention relates to (co)polymers which contain at least one repeat chain unit of the general formula (1) or (2) and optionally contain repeat units of the general formula (3) 
in which
L1 and L2 mean a photoluminescent residue,
wherein the proportion of structural units of the formulae (1) and/or (2) is in each case 0.5 to 100 mol. %, and (3) 0 to 99.5 mol. %, and the molar percentages add up to 100,
to the use thereof for the production of electroluminescent devices and to the electroluminescent devices.
                            本发明涉及(共)聚合物,其中至少包含一个通式(1)或(2)的重复链单元,可选地包含通式(3)的重复单元,其中L1和
L2表示光致发光残基,其中通式(1)和/或(2)的结构单元比例在每种情况下为0.5至100摩尔%,(3)为0至99.5摩尔%,而摩尔百分比相加为100,用于制造电致发光装置以及电致发光装置。
