1. Field of the Invention
Aspects of the present invention relate to a fluorine-containing compound and an organic light-emitting device employing the same. More particularly, aspects of the present invention relate to a fluorine-containing compound that has electrical stability, good charge transport capability, and a high glass transition temperature and that can prevent crystallization. Aspects of the present invention further relate to an organic light-emitting device employing an organic layer including the fluorine-containing compound.
2. Description of the Related Art
Electroluminescent (EL) devices are self-emitting devices that have advantages such as a wide viewing angle, good contrast, and a rapid response time. EL devices are classified into inorganic EL devices, which include an emitting layer formed of an inorganic compound, and organic EL devices, which include an emitting layer formed of an organic compound. Organic EL devices show better brightness, driving voltage, and response speed characteristics compared to inorganic EL devices, and can create polychromatic light. Thus, extensive research into organic EL devices has been conducted.
Generally, organic light-emitting devices have a stacked structure including an anode, an organic light-emitting layer, and a cathode. A hole injection/transport layer or an electron injection layer may be further disposed between the anode and the organic light-emitting layer or between the organic light-emitting layer and the cathode to form an anode/hole transport layer/organic light-emitting layer/cathode structure, an anode/hole transport layer/organic light-emitting layer/electron transport layer/cathode structure, or the like.
A polyphenyl hydrocarbon and an anthracene derivative have been described as material for forming a hole transport layer (U.S. Pat. Nos. 6,596,415 and 6,465,115).
However, organic light-emitting devices including hole transport layers formed of currently available hole transport layer materials have disadvantages in terms of lifetime, efficiency, and power consumption characteristics, and thus, there is room for improvement in conventional organic EL devices.
