Patent
Organic electroluminescent element material and organic electroluminescent element using the same
TL;DR: In this article, a cyclic organic compound is expressed by the formula, and composed, for example, by the use of a naphthoquinone derivative, a Grignard's reagent and a lithiation reagent or diaryl benzoflane.
Patent
Luminescent material for organic electroluminescent element and organic electroluminescent element produced by using the same
TL;DR: In this article, the authors proposed a method to improve luminous intensity, luminous efficiency, and stability in repeated use by reacting a dihalide of a specified divalent residue, a secondary amine derivative, potassium carbonate and a catalyst in a solvent.
