COMPOUND AND METHODS FOR PREPARING THE SAME AND ITS APPLICATIONS

摘要

The present invention provides a compound having the following formula (I):;;R2 is an electron withdrawing group; A represents a structure with 0 to 20 benzene rings connected in sequence, R1 is an electron donating group or to form a cyclic electron donating group with parts of carbon atoms of the last benzene ring. The present invention also provides an organic layer of OLED devices. The present invention also provides a method for synthesizing the compound represented by formula (I). The OLED material with the novel structure provided by the present invention can be applied to an electron-transporting layer, a light emitting layer, a hole transporting layer. Hence, the display devices consisting of the aforesaid OLED material have the advantages of swift response, low power consumption, and wide viewing angle.
