Title:
Material for light emitting layer and organic electroluminescent device using it
Document Type and Number:
Japanese Patent JP6341315
Kind Code:
B2
Abstract:
By using, as a material for light emitting layers, an anthracene compound represented by general formula (X) and having two phenyl groups bonded at the 9- and 10-positions, wherein specific aryl groups (phi) are substituted at the 2- and 5-positions, at the 3- and 4-positions or at the 2-, 4- and 5-positions of one phenyl group (which is bonded with the anthracene at the 1-position thereof), an organic electroluminescent element having excellent driving voltage, luminous efficiency and element service life can be provided. (In the formula, phi represents a phenyl group, a naphthyl group, a phenanthryl group or a triphenylenyl group; each of Ar and Ar1 represents an optionally substituted aryl group; and R represents an alkyl group or a cycloalkyl group.)
