    摘要: Disclosed is a method for producing a block copolymer which comprises two or more blocks composed of aromatic units having different basic structures from each other and has a high molecular weight, a narrow chain length distribution and a narrow molecular weight distribution. Also disclosed is a block copolymer produced by the method. The method for producing a block copolymer comprises the step of sequentially reacting two or more aromatic compounds which are selected from aromatic compounds represented by a specific general formula and are different in the group Ar, in the presence of a nickel complex containing a phosphine compound represented by a specific general formula or a palladium complex containing a phosphine compound represented by a specific general formula to thereby form blocks comprising the aromatic compounds sequentially, wherein the two or more aromatic compounds are reacted in descending order of parameter of aromatic ring charge.

    摘要: In an organic EL device 1, when a voltage is applied across an anode 3 and a cathode 5, holes are moved in a hole transport layer 41 and electrons are moved in an electron transport layer 43, and the holes and the electrons are recombined in a light emitting layer 42 to emit light. A light emitting material is used to form the light emitting layer 42. When the light emitting layer 42 is formed using the light emitting material, the light emitting layer contains one or more kinds of metallic impurities, but an amount of a metallic impurity of which content is the largest among the metallic impurities contained in the layer is 2.5 ppm or less, or when the light emitting material is dissolved in a liquid so that the concentration thereof becomes 2.0 wt%, the liquid contains one or more kinds of metallic impurities, but an amount of the metallic impurity of which content is the largest among the metallic impurities contained in the liquid is 50 ppb or less. By using such a light emitting material, the decrease of light-emission luminance of the organic EL device 1 can be suppressed.
