- ORGANIC LIGHT DEVICE AND ORGANIC LIGHT COMPOUND FOR THE SAME
-
PURPOSE: An organic photoelectric element is provided to obtain high luminous efficiency, luminance, color purity, and remarkably improved luminous life time. CONSTITUTION: An organic photoelectric element comprises a first electrode, a second electrode, and at least one organic layer between the first electrode, and the second electrode, the organic film comprises an organic luminous compound in chemical formula L. In chemical formula L, R1 and R2 are different each other, and is respectively selected from hydrogen, deuterium, C1-40 alkyl, C2-40 alkenyl, C2-40 alkynyl, C5-40 aryl, C5-40 heteroaryl, C5-40 aryloxy, C1-40 alkyloxy, C5-40 arylamino, C5-40 diarylamino, C6-40 arylalkyl, C3-40 cycloalkyl and C3-40 heterocycloalkyl, or is a group forming a fused aliphatic ring, a condensed aromatic ring, a condensed hetero aliphatic ring, or a condensed hetero aromatic ring with a neighboring group.

- Improved synthesis of aryl-substituted anthracenes and heteroacenes
-
(Chemical Equation Presented) A Bronsted acid-catalyzed highly efficient construction of substituted arylanthracenes and heteroacenes is described, which is assumed to be initiated through the facile formation of a benzylic cation intermediate. This method offers several advantages in comparison with known aromatic cyclodehydration reactions such as high selectivities, mild reaction conditions, and easily accessible starting materials.
