    • Novel electrophosphorescent copolymers of the composition [A 1 ] x1 , [A 2 ] x2 , [A 3 ] x3 , [A 4 ] x4 , [A 5 ] x5 wherein the structural units A 1 , A 2 , A 3 , A 4 and/or A 5 are in blocks or at random, and the copolymer is linear or crosslinked, and A 1 is an organic radical of a phosphorescent light emitting moiety; A 2 is an organic radical providing host functionality; A 3 is an organic radical providing electron transport functionality; A 4 is an organic radical providing hole transport functionality; A 5 is a radical derived from aliphatic or aromatic organic monomers; x1 is a number from 1 to about 1000; x2, x3, x4 and x5 independently are numbers from 0 to about 100 000, with the proviso that the sum (x1 + x2 + x3 + x4 + x5) is at least 5, especially greater than 9; are characterized in that A 1 contains a metal benzotriazole complex moiety or A 2 is selected from repeating unit(s) of the formulae (III), (IV), where the symbols are as defined in claim 1. The novel copolymers are useful as active materials e.g. in electroluminescent devices.
