Polymers with fluoranthene-based repeat units are new. Polymers containing repeat units of formula (I) are new. a = 0-3; R1-R3 = H, 1-20C alkyl, (optionally with one or more Si, N, P, O or S atoms), 6-30C (preferably 6-14C) aryl, 4-14C heteroaryl with at least one S or N atom, -N(6-14C aryl)2 or the group Y1; Y1 = vinyl, (E)- or (Z)-phenylethenyl, (meth)acryloyl, methyl styryl, vinyloxy, glycidyl, phenylethynyl or the group -Phe-O-Y2; Phe = 1,4-phenylene; Y2 = vinyl, (E)- or (Z)-phenyl-ethenyl, (meth)acryloyl, methyl styryl, vinyloxy or glycidyl, optionally with one or more groups Y1 or Y2 crosslinked together. Independent claims are also included for: (1) a method (M1) for the production of (I) from monomers of formula (II) by reaction in the presence of nickel or palladium compounds (2) monomers of formula (II) with a halogen or esterified sulfonate group on ring C (preferably at position 8 of the fluoranthene system) and a boron-containing group (c) (see below) on ring B (preferably at position 3) (i.e. monomers III) (3) a method for the preparation of (III) from the corresponding compounds with halogen or sulfonate groups, by metalation with at least 2 or at least 4 equivalents of a strong organometallic base followed by reaction with 1 or 2 equivs. of boron compounds of formula (V) (4) a method (M2) for the production of (I) by the photochemical or thermal polymerisation of monomers of formula (II) with no X1 or X2 groups (i.e. monomers VI) (5) films containing or consisting of (I) (6) organic electro luminescent diodes based on (I). X1, X2 = (a) halogen, (b) esterified sulfonate, or (c) boron-containing groups of formula -B(O-(C(R6)2)n)-O-), using either one monomer of formula (II) in which X1 is a group (a) or (b) and X2 is (c), or at least two different monomers (II), one of which has two (a) and two (b) groups, or one of each, and the other monomer has two groups (c), with (a + b) and (c) in a mol ratio of (0.8:1)-(1.2:1) ; R6 = H or 1-20C alkyl; n = 2-10; X5 = 1-6C alkoxy.
