Use of quinoid bisimidazoles and their derivatives as dopant for doping an organic semi-conductor matrix material

摘要

Use of quinoid bisimidazole (I) and its derivatives as doping agent for doping an organic semiconducting matrix material, as charge injection layer, matrix material, an electrode material or as a memory material in an electronic or optoelectronic components, is claimed. Use of quinoid bisimidazole of formula (I) and its derivatives as doping agent for doping an organic semiconducting matrix material, as charge injection layer, matrix material, an electrode material or as a memory material in an electronic or optoelectronic components, is claimed. Y1 : H, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted conjugated hydrocarbon chain with alternating C-C-unit- and double bond, halo, CN, pseudohalo, N, F and perfluoroalkyl, carboxylic acid and its derivative or sulfonic acid and its derivative. Where the two adjacent Y1 components of an aromatic ring system are annelated at the imidazole ring, preferably the aromatic ring system annelated at the imidazole ring is substituted. Independent claims are included for: (1) an organic semiconducting material comprising at least an organic matrix compound and (I) as doping agent; and (2) an electronic or optoelectronic components comprising (I) as an electronically functional effective area.
