Description

The present invention relates to a novel anthracene compound and an organic electroluminescent device comprising the anthracene compound.

Conventionally, an inorganic electroluminescent element has been used as a panel-type light source such as a backlight. However, in order to drive the light emitting element, an alternating high voltage is required. Recently, an organic electroluminescence element (organic electroluminescence element: organic EL element) using an organic material as a luminescent material has been developed [see, for example, Non-Patent Document 1].

  An organic electroluminescent device has a structure in which a thin film containing a fluorescent organic compound is sandwiched between an anode and a cathode. By injecting electrons and holes into the thin film and recombining them, an exciton (Exington) ) And emits light using light emitted when the exciton is deactivated. The organic electroluminescent element can emit light at a low direct current voltage of several volts to several tens of volts, and various colors (for example, red, blue, green) can be selected by selecting the type of the fluorescent organic compound. ) Can be emitted. The organic electroluminescent device having such characteristics is expected to be applied to various light emitting devices, display devices and the like. However, in general, the luminance is low, which is not sufficient for practical use.

  As a method for improving the light emission luminance, an organic electroluminescent device using tris (8-quinolinolato) aluminum as a host material and a coumarin derivative or a pyran derivative as a guest compound (dopant) has been proposed as a light emitting layer. [See Non-Patent Document 2]. In addition, organic electroluminescent elements using anthracene derivatives as the material of the light emitting layer have been proposed (see, for example, Patent Document 1 and Patent Document 2). Furthermore, an organic electroluminescent element using an anthracene derivative as a guest compound of the light emitting layer has also been proposed (see, for example, Patent Document 3 and Patent Document 4).

However, it cannot be said that these light emitting elements also have sufficient light emission luminance and light emission lifetime, and at present, further higher luminance and longer life are desired.
