Abstract:
1. A mixture comprising (A) 5-99.5% by weight of at least one conjugated polymer (POLY2) comprising 1-100 mol % of units of the formula (XXXII), R Aryl are identical or different on each occurrence and are each an aromatic or heteroaromatic ring system which has from 2 to 40 carbon atoms and may be substituted or unsubstituted or a substituted or unsubstituted stilbenzylene or tolanylene unit; the possible substituents R R R R m is identical or different on each occurrence and is 0, 1 or 2; o is identical or different on each occurrence and is 0, 1 or 2, with the proviso that o must not be 0 when m=2; r is identical or different on each occurrence and is 0 or 1, z is identical or different on each occurrence and is 0, 1, 2 or 3; and (B) 0.5-95% by weight of at least one organic or organometallic dendrimer or at least one low molecular weight molecule having a molecular weight in the range<10 000 (COMP1) which in a pure or dilute film is capable of fluorescence or phosphorescence and which has adequate solubility in suitable solvents to be able to be processed in the blend together with the polymer from a solution in this solvent.
