TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The component is an organic light emitting diode or organic photovoltaic element. The organic light emitting diode is composed of anode, the first layer of the layered body, the further layer of the layered body, optionally emitter layer, optionally electron injection layer and cathode.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation: No preparation method is given.    TECHNOLOGY FOCUS - POLYMERS - Preferred Method: The conductive polymer is applied on the substrate in the form of a dispersion comprising the conductive polymer and a dispersing agent. The method produces a self assembled monolayer during the application of (I) on the first layer in step (ii). Preferred Components: The conductive polymer comprises polythiophene and a polymer that is functionalized with acid groups. The polythiophene is poly(3,4-ethylenedioxythiophene). The polymer that is functionalized with acid groups is polystyrene sulfonic acid. The weight ratio of the polymer that is functionalized with acid groups and the polythiophene in the first layer is 0.5:1-50:1. The total weight of the polythiophene and the polymer that is functionalized with acid groups, in the first layer and in the dispersion is at least 50 wt.%, based on the total weight of the first layer. The further layer is formed from a self assembled monolayer. The dispersion comprises complexes containing poly(3,4-ethylenedioxythiophene) and polystyrene sulfonic acid. Preferred Definitions:    R1 = -C6H12-;    R, R2, R3 = H;    Ar1 = substituted naphthyl moieties of formula (II), phenyl or naphthyl; and    R4 = -R1-NR2R3.    SPECIFIC COMPOUNDS - 4 Compounds (I) are disclosed i.e. N,N'-diphenyl-N,N'-di-4-(6-bromohexyl)naphthyl benzidine of formula (Ia), N,N'-diphenyl-N,N'-di-4-(6-aminohexyl)naphthyl benzidine, N,N'-diphenyl-N-4-(6-bromohexyl)naphthyl-N'-4-naphthyl benzidine, and N,N'-diphenyl-N-4-(6-aminohexyl)naphthyl-N'-4-naphthyl benzidine.    EXAMPLE - N,N'-diphenylbenzidine (1.01 g), 1-bromo-4-(6-bromohexyl)-naphthalene (2.80 g) and sodium tert-butoxide (0.43 mg) were suspended in anhydrous toluene (60 ml) and heated to reflux. Then a solution of bis(dibenzylideneacetone)palladium(0) (68 mg) and tri-tert-butylphosphine (24 mu l) in anhydrous toluene (30 ml) was added to the reaction mixture at 105 degrees C. Then the obtained solution was stirred for 42 hours at 110 degrees C. Then the solution was cooled and worked up to obtain (Ia).
