- Organic light-emitting material, preparing method thereof and organic light-emitting device
-
The invention discloses an organic light-emitting material, a preparing method thereof and an organic light-emitting device. The organic light-emitting material comprises oxadiazole benzodioxazole. The organic light-emitting material comprises the oxadiazole benzodioxazole, has high planarity and strong visible pi-pi* absorption capacity and meanwhile has high-quantum-yield fluorescent transmission capacity; thus, the oxadiazole benzodioxazole with a large pi conjugation system has the efficient electronic transmission characteristic, can increase the charge migration efficiency as an efficient electron withdrawing group and effectively improves the light-emitting efficiency of the organic light-emitting device.

- Organic Compound, Benzoxazole Derivative, and Light-Emitting Element, Light-Emitting Device, and Electronic Device Using Benzoxazole Derivative
-
Novel benzoxazole derivatives are provided to reduce driving voltage of light-emitting elements, and to reduce power consumption of light-emitting elements, light-emitting devices, and electronic devices. A benzoxazole derivative represented by the general formula (G1) is provided. Since the benzoxazole derivative represented by the general formula (G1) has an electron-injecting property, the benzoxazole derivative can be suitably used for light-emitting elements, light-emitting devices, and electronic devices.

- Benzoxazole Derivative, and Light-Emitting Element, Light-Emitting Device, and Electronic Device Using the Same
-
An object is to provide a novel benzoxazole derivative. Another object is to reduce driving voltage of a light-emitting element. Still another object is to reduce power consumption of a light-emitting element, a light-emitting device, and an electronic device. A benzoxazole derivative represented by General Formula (G1) is provided. The benzoxazole derivative represented by General Formula (G1) has an electron-injecting property and an electron-transporting property; accordingly, it can be favorably used for a light-emitting element, a light-emitting device, and an electronic device.
