The present disclosure relates to an organic compound having the following structure, and an organic light emitting diode (OLED) and an organic light emitting device including the organic compound. Applying the organic compound into an emissive layer makes the OLED and the organic light emitting device lower their driving voltage, improves their luminous efficiency and color purity.

Organic compound, organic light emitting diode and organic light emitting device having the organic compound

The present disclosure relates to an organic compound having the following structure, and an organic light emitting diode (OLED) and an organic light emitting device including the organic compound. The organic compound includes an electron donor moiety separated from an electron acceptor moiety, thus has delayed fluorescent properties. Applying the organic compound into an emissive layer makes the OLED and the organic light emitting device can allows the OLED and the organic light emitting device to improve their luminous efficiency.

Organic compound, organic light emitting diode and organic light emitting device including the compound

The present disclosure relates to an organic compound having improved luminescent properties, an organic light emitting diode and organic light emitting device including the organic compound, the organic compound having the following structure. The organic compound is a bipolar compound having both a p-type moiety and an n-type moiety and has high energy level, large energy bandgap and improved thermal stability. Applying the organic compound into an emissive layer of the OLED allows holes and electrons to be recombined at whole area of an emitting material layer, and thereby enhancing the luminous efficiency and the luminous lifetime of the OLED.

Organic compound having improved luminescent properties, organic light emitting diode and organic light emitting device including the organic compound

The present disclosure relates to an organic compound having the following structure, and an organic light emitting diode (OLED) and an organic light emitting device including the organic compound. The organic compound is a bipolar compound having a p-type moiety and an n-type moiety and has high energy level and proper energy bandgap for an emissive layer of the OLED. As the organic compound is applied into the emissive layer, the OLED can maximize its luminous properties as holes and electrons are recombined uniformly over the whole area in an EML.
