COMPOSITION FOR hole injection or hole transport layers in electroluminescent devices, organic solar cells, organic laser diodes, organic thin-film transistors or organic field effect transistors or for electrodes or conductive coating, electroluminescent devices, and organic light emitting diodes

摘要

A composition (C1) comprises at least one polythiophene (a) containing recurring units; at least one polymer (b) that is different from (a) and which contains sulfonate salt or carboxylate sa and at least one polymer (c) that is different than (a) and (b) and which contains sulfonate salt or carboxylate salt and is selected from partially fluorinated polymer and/or perfluorinated polymer. A composition (C1) comprises at least one polythiophene (a) containing recurring units of formula (I); at least one polymer (b) that is different from (a) and which contains SO 3 -M + or COO -M +; and at least one polymer (c) that is different than (a) and (b) and which contains SO 3 -M + or COO -M + and is selected from partially fluorinated polymer and/or perfluorinated polymer. A : optionally substituted 1-5C alkylene; R : linear or branched 1-18C alkyl, 5-12C cycloalkyl, 6-14C aryl, 7-18C aralkyl, 1-4C hydroxyalkyl or hydroxyl; x : 0 - 8;and M : H, Li, Na, K, Rb, Cs or NH 4. An independent claim is included for an electroluminescent (EL) arrangement comprising either at least one layer selected from hole-injecting layer and hole-transporting layer where hole-injecting layer and hole-transporting layers each containing (C1); or a substrate, at least two electrode layers, at least one emitter layer and at least one hole-injecting layer where at least one electrode layer abuts the substrate, the emitter layer is interposed between two electrode layers and at least one hole-injecting layer is interposed between one of the electrode layers and the emitter layer and further the hole-injecting layer containing (C1).
