| abstract |
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) n in which n L 1 and L 2 mean a photoluminescent residue, n 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, n to the use thereof for the production of electroluminescent devices and to the electroluminescent devices. |
