Abstract:
PURPOSE: A carbazole compound and organic electro luminescence device using the same are provided to easily perform wet and dry coating and to ensure optical and electrical stability. CONSTITUTION: A carbazole compound is denoted by chemical formula 1. An organic electro luminescence device comprises a first electrode, second electrode, and organic compound layer between the first and second electrodes. The organic compound layer contains the carbazole compound. The layer containing carbazole comound is a light emitting layer, hole transport layer, or hole injection layer.
Abstract:
PURPOSE: A high functional organic semiconductor compound based on 2,7-bis-(vinyl)[1]benzothieno[3,2-b]benzothiophene is provided to ensure high on/off ratio and filed-effect mobilities. CONSTITUTION: An organic semiconductor compound of chemical formulas 3 to 9 is synthesized by reacting phosphonate of chemical formula 1 with aldehyde derivative of chemical formula 2. In chemical formulas 1 and 2, A is cyclic alkyl group, phenyl group, phenyl group substituted with C1-C12 alkyl group, thiophenyl group, thiophenyl group substituted with C1-C12 alkyl, naphthyl group, naphthyl group substituted with C1-C12 alkyl, non-phenyl group, non-phenyl group substituted with C1-C12 alkyl, anthracenyl group, anthracenyl group substituted with C1-C12 alkyl, phenanthrenyl group, or phenanthrenyl group substituted with C1-C12 alkyl group. An electric element comprises the organic semiconductor thin film of chemical formulas 3 to 9.
