Claim:
A process for preparing polyfluoranthenes comprising repeating units of the general formula I which comprises: a) preparation of a monomeric fluoranthene derivative of the formula IIa by reaction of a compound of the formula III with an alkynyl compound of the formula IV and subsequent carbon monoxide elimination; b) optionally, reaction of the monomeric fluoranthene derivative of the formula IIa to form a monomeric fluoranthene derivative of the formula IIb c) polymerization of the monomeric fluoranthene derivative of the formula IIa or IIb, optionally, together with at least one further comonomer selected from the group consisting of further fluoranthene derivatives of the formula IIa or IIb which are different from the first fluoranthene derivative of the formula IIa or IIb, aromatic, fused aromatic and heteroaromatic compounds which each have two groups X 5 and X 6 which can be polymerized with the groups X 1 and X 2 of the fluoranthene derivative of the formula IIa or the groups X 3 and X 4 of the fluoranthene derivative of the formula IIb; where: R 1 , R 2 , R 3 R 4 , R 5 , R 6 are each, independently of one another, H, an alkyl radical, an alkynyl radical, an aryloxy radical, an aromatic radical, a fused aromatic ring system, a heteroaromatic radical, —CH═CH 2 , trans- or cis-CH═CH—C 6 H 5 , acryloyl, methacryloyl, methylstyryl, —O—CH═CH 2 , glycidyl, where Y is acryloyl, methacryloyl, ortho- or para-methylstyryl; X 1 and X 2 are each a halogen selected from the group consisting of F, Cl, Br and I, or NO 2 ; X 3 and X 4 are each a halogen selected from the group consisting of F, Cl, Br and I; an esterified sulfonate; or a boron-comprising radical of the formula —B(O[C(R 7 ) 2 ] n —O), where the radicals R 7 are identical or different and are each, independently of one another, H or C 1 -C 20 -alkyl, and n is an integer of from 2 to 10; X 5 and X 6 are each a halogen selected from the group consisting of F, Cl, Br and I; an esterified sulfonate; or a boron-comprising radical of the formula —B(O—[C(R 7 ) 2 ] n —O), where the radicals R 7 are identical or different and are each, independently of one another, H or C 1 -C 20 -alkyl, and n is an integer of from 2 to 10; and wherein only one of X 3 or X 4 is a halogen.
