Polymers containing spiro atoms which can be used as electroluminescence materials, suitable for use in ligerting or display devices, and which improve the property profile of these devices. Specifically, a conjugated polymer comprising structural units of the formula (I), <IMAGE> (I where the symbols and indices have the following meanings: D, E, F1, G are identical or different, and are -CR1R1-, -O-, -S-, -NR3- or a chemical bond; Ar1, Ar2 are carbocycles or heterocycles; U1, V1 are identical or different, and are -CR5=CR6-, -CR7R8-, -CR9R10-CR11R12-, -NR13-, -SiR14R15-, -O-, -S-, -SO-, -SO2-, -CO- or a chemical bond; Ar5, Ar6, X, Y1 are identical or different, and are cyclic or acyclic, conjugated hydrocarbons and X and/or y1 can also be H or R1; m is 1, 2, 3 or 4; n, p are identical or different and are 0, 1, 2, 3 or 4, is suitable as an electroluminescence material. |
