Abstract:
1. 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 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 where: R R X X X wherein only one of X
