NOVELTY - Organic semiconductor layer comprises at least one matrix material and at least one doping material, where the doping material is made of a substituted cyclopropane compound (I) and the matrix material comprises 4-(4-(4-(bis(4-phenylphenyl)amino)phenyl)phenyl)-N,N-bis(4-phenylphenyl)aniline or 4-(4-(4-(bis(4-phenylphenyl)amino)phenyl)phenyl)-N,N-bis(4-phenylphenyl)aniline (in which at least one hydrogen atom is substituted by aromatic, heteroaromatic and/or alkyl with 1-20 carbon atoms).    USE - The organic semiconductor layer is useful in an organic component, preferably a light-emitting component or an organic solar cell.    ADVANTAGE - The organic semiconductor layer exhibits reduced absorption, improved conductivity, improved thermal stability and improved overall performance compared to a N,N-diphenyl-(1,1-biphenyl)-4,4-diamine layer.    DETAILED DESCRIPTION - Organic semiconductor layer comprises at least one matrix material and at least one doping material, where the doping material is made of a substituted cyclopropane compound of formula (I) and the matrix material comprises 4-(4-(4-(bis(4-phenylphenyl)amino)phenyl)phenyl)-N,N-bis(4-phenylphenyl)aniline or 4-(4-(4-(bis(4-phenylphenyl)amino)phenyl)phenyl)-N,N-bis(4-phenylphenyl)aniline (in which at least one hydrogen atom is substituted by aromatic, heteroaromatic and/or alkyl with 1-20 carbon atoms).    X = R1-CH2-CN; and    R1 = aryl or heteroaryl, where aryl and heteroaryl are substituted, preferably are substituted completely with one electron-poor substituent.    INDEPENDENT CLAIMS are also included for:    (1) an organic component comprising the organic semiconductor layer; and    (2) a mixture comprising at least one matrix material and at least one doping material for producing the doped semiconductor layer, where the doping material is made of (I) and the matrix material comprises benzene compound of formula (II).    A = substituted diphenyl-amine of formula (III);    n = 2 or 3;    X1 = CH3, tert-butyl or phenyl; and    Y1 = optionally substituted tetraphenylmethane, optionally substituted phenanthrene, ((4-isopropylphenyl)(p-tolyl)methylene)dibenzene, 9-isopropylphenanthrene or biphenyl.
