Description

The electroluminescent device of anthracene derivant and this derivative of use

Technical field

The present invention relates to a kind of new organic compound and a kind of organic electroluminescent (hereinafter electroluminescent will be called EL) device that uses this organic compound.More particularly, the present invention relates to a kind of as the organic EL device constituent material anthracene derivant and use this anthracene derivant and present high-luminous-efficiency and the organic EL device of superior heat resistance performance.

Technical background

Utilize the electroluminescent device of luminescence phenomenon in the electric field very high because of the luminous effect shows from resolving power, have excellent shock resistance because of it is entirely solid state device.Therefore, organic EL device can be applicable to the back illumination and the area source field of thin-film display and liquid-crystal display.

The El element of practical application at present is the El element of decentralized, because dispersion-type el device needs tens volts or higher and 10 kilo hertzs or higher voltage of alternating current, makes that the driving circuit of El element is very complicated.
