Abstract: The present invention provides sugar beet pectin (modified sugar beet pectin) having improved or enhanced emulsifying properties and emulsion stability, compared to natural sugar beet pectin. Also provided is a method for producing the modified sugar beet pectin. The modified sugar beet pectin contains a water-insoluble component, and has a higher molecular weight after high-pressure homogenization than ordinary sugar beet pectin. The water-insoluble component absorbs water to form a hydrogel when the modified sugar beet pectin is dispersed in water at 25° C. to a final concentration of 0.1 mass %.
Abstract: Disclosed is an organic electroluminescent device including a substrate, a first and a second electrode, and an emitting layer formed between the first electrode and the second electrode. The emitting layer includes a plurality of materials which is a blue emitting material using a following chemical formula as dopant. In this case, at least one of A1 and A2 is selected from a substituted or non-substituted aromatic group, a heterocyclic group, an aliphatic group, and hydrogen.
