<p>The aim is achieved by a method in which a nickel or palladium catalyst is added to a solution of an organometallic complex, wherein the organometallic complex is produced by adding metallic Zn or Mg to a monomer solution, or by adding a reducing agent to a monomer solution and either Zn2+ or Mg2+ salt, wherein lithium naphthalenide or sodium naphthalenide or potassium naphthalenide is used as the reducing agent, and wherein a p-conjugated system of the formula X-B-A-B-X is used as the monomer, wherein a core based on electron acceptor material containing naphthalene-1, 4, 5, 8-tetracarboxylic acid bisimide (NDI) or perylene tetracarboxylic acid bisimide (PDI) or pyromellitic bisimide (PMI) or diketopyrrolopyrrole (DPP) is used as A, and an aromatic or heteroaromatic or condensed aromatic or condensed heteroaromatic group based on substituted or unsubstituted benzene, fluorene, thiophene, bithiophene, pyrrole, thieno[2,3-b]thiophene, 4H-cyclopenta[2,1-b:3,4-b']dithiophene, or dithieno[[3,2-b:2',3'-d]silole derivatives is used as B, and a halogen is used as X.</p> |
