Patent number: 11258020
Abstract: A method produces cross-linked hole-conducting electric layers by converting functionalized p-dopants. The functionalized p-dopants are organic metal complexes containing at least one central atom and organic ligands, wherein the central atom is selected from a metal of the groups 6-15 of the periodic table, and at least one of the organic ligands is selected from the following formulas I-V, in which E independently of one another is oxygen, sulfur, selenium, or N(E1)x, and each Rv has at least one functionalizing group selected from the group RF including —OH, —COOH, —NH2, —NHR?, halogen, C2-C40-alkenyl, -dienyl, -alkinyl, -alkenyloxy, -dienyloxy, -alkinyloxy, acrylic acid, oxetan, oxiran, silane, acrylic acid, anhydride, and cyclobutane or consists of the groups, and G=C(RF)uHvFw where u+v+w=3 and n=1-4.
