  • Publication number: 20130344635
    Abstract: It is an object to provide a composition in which an anthracene derivative is dissolved and a technique in which a thin film that has a favorable film quality is formed by a wet process using the composition. In addition, it is another object to manufacture a highly reliable light-emitting element using the composition at low cost with high productivity. A composition having a solvent and an anthracene derivative having one anthracene structure and one carbazolyl group which is bonded to the anthracene structure directly or through a phenyl group is formed. A thin film with a favorable film quality can be formed by a wet process using the composition. Accordingly, a highly reliable light-emitting element can be manufactured using such a thin film.

  • Patent number: 8481174
    Abstract: Provided are an organic light-emitting compound that is a diarylethene derivative represented by Formula 1, and an organic electroluminescent (EL) device using the organic light-emitting compound, and a method of manufacturing the organic EL device: where R1, Ar1, Ar2, Ar3, Ar4, Ar5, Ar6, k, l, m, and n are the same as defined in the specification. The organic light-emitting compound contains a cis-diarylethene group linked with an aliphatic ring, and thus crystallization of the organic light-emitting compound is unlikely to occur and the compound is highly soluble to organic solvents and easily provides liquid formulation with organic solvents. Thus, the organic light-emitting compound can easily be used in organic EL devices. An organic EL device manufactured using the compound can have a thermostable layer and thus has improved light-emitting properties in term of superior turn-on voltage, efficiency, color purity, etc.
